Ultra Trace Sensor

The analyzer incorporates an electrochemical ultra trace O2 sensor exclusively designed by TET/AI (U.S. Patent #5,085,760). The sensor shows exceptionally high sensitivity for O2 and remarkable long-term stability. The highly accurate sensing element of the sensor enables it to detect as low as 0.5 PPB of O

The components of the sensor are shown in Figure 2-2. The main body of the sensor is made of clear acrylic. The sensor has a U-shaped profile with an open top end. The left-hand wall of the sensor has a circular aperture for mounting the O2-sensing cathode. A high surface area cadmium anode is inserted through the top stainless steel plate. A fine porous frit disc is mounted at the bottom of the sensor in order to remove any dissolved O2 by continuously sparging the electrolyte with O2 free gas. A baffle plate is inserted between the sparger and the sensing electrode to minimize the noise level caused by the sparger.

The sensing cathode used in the sensor is a high surface-area metal-catalyzed gas diffusion electrode, with a surface area of 150–180 m2/g. A 0.4 mg/cm catalyst load provides an effective cathode surface area of up to 600 times the geometric area of the cathode. This produces a very high signal output per unit concentration of O2; hence, an excellent signal-to-noise ratio is achieved even at the highest sensitivity.

The metal-catalyzed gas-diffusion electrode consists of a hydrophobic Tefloncarbon gas diffusion backing layer and a Teflon-carbon metal catalyst layer bonded together. The thickness of the catalyst layer is approximately one-tenth of the gas diffusion layer. The overall thickness of the cathode is approximately

0.5 mm. The cathode is held against the sensor body by a polyethylene ring. The catalyst

layer of the cathode is exposed to the electrolyte phase; the hydrophobic backing layer is exposed to the gas to be analyzed. The cathode assembly is sealed by placing a polypropylene O-ring between the stainless steel plate, containing stainless steel gas inlet and outlet tubes, and the sensor body.

Chapter 2Chapter 2

Chapter 2

Chapter 2Chapter 2

The electrolyte in the sensor is continuously purged by bubbling the zero gas (generated by passing the sample gas through the built-in scrubber) through the fine porous frit mounted in the inner floor of the sensor. Sparging of the electrolyte removes most of the dissolved O

from the electrolyte, reducing the

background signal.

Ultra Trace Sensor Operation

The gas to be analyzed enters the cavity through an inlet tube between the cathode and the stainless steel plate, and exits through the outlet tube. During this process, the gas diffuses through the gas wicks of the hydrophobic backing layer, and reaches the catalyst surface where O2 present in the gas mixture reacts by the following mechanism:

O2 + 2H2O + 4e- → 4OH

Due to the high surface area of the catalyst, most of the O2 reacts at the cathode surface and a very small amount of O2 dissolves in the bulk electrolyte. The continuous sparging of the electrolyte with zero gas does not allow the O concentration to build up in the bulk electrolyte. The amount of O2 that reaches the catalyst surface is proportional to the partial pressure of O2 in the gas mixture.

Cd → Cd+2 + 2e

The electrons released at the anode surface flow to the cathode surface via an external circuit. This current is measured and used to determine the O concentration in the gas mixture. The resulting current is directly proportional to the O2 level in the gas mixture.

The current output of the sensor changes with temperature therefore, in order to minimize the effects of ambient temperature variation on the current output, the sensor is housed in a temperature-controlled oven maintained at 28°C ±2°C. Variations in temperature affecting the sensor are detected by a resistive thermal device (RTD) attached to the sensor, which signals the temperature controller to adjust the oven temperature accordingly.

A thermistor installed in the sensor monitors electrolyte temperature. Changes in electrolyte temperature above 30°C are relayed to the microprocessor, which adjusts the current output through a compensation algorithm.

NOTE: Since the gas to be analyzed does not flow through the bulk

electrolyte of the sensor, the probability of contaminating the electrolyte by the particulates (if any) in the sample gas is very low. This eliminates the requirements for frequent replacement of sensor electrolyte. This is in contrast to Hercsh type galvanic cells where gas is bubbled through the electrolyte and frequent replacement of electrolyte (3-6 month intervals) is essential to maintain sensor performance.

(anode)

Faradaic Calibrator

The analyzer may be calibrated by using either the internal Faradaic calibrator or an external span gas. The calibration using an external span gas is simple and self-explanatory. The internal calibrator generates O2 at a precisely controlled rate. The unique design of the calibrator allows repeated and reliable calibration of the analyzer.

Faradaic Calibrator Components

Figure 2-3 illustrates major calibrator components. The calibrator is comprised of a top electrode assembly and a bottom mounting block containing a cup for electrolyte. An O-ring is used to make a leak-free seal between these two components.

The two platinum/gold wire electrodes are attached to a feed-through header, which is sealed to the stainless steel plate. The two electrodes are wrapped around a porous polyethylene rod. The bottom end of the porous polyethylene rod is submerged into the pool of electrolyte. Capillary action causes the electrolyte to fill the pores, keeping the electrodes wet, which helps to maintain the ionic conductivity between the two electrodes.

The calibrator is based on Faraday’s Law of Electrolysis. When applied to the electrolysis of water, it states that the rate at which oxygen is generated is directly proportional to the quantity of electric current flowing through the electrodes. Based on this, the following formula is derived to determine the current required to generate a mixture with the desired oxygen concentration (PPM) and flow rate (SCCM).

The desired O2 concentration is entered through the calibration menu, and the mass flow controller provides the flow rate of O2-free zero gas through the calibrator. The required current for the electrolysis of water is calculated by the microprocessor and then supplied to the calibrator electrodes.

A calibrator bypass uses zero gas to flush out any O2 that has seeped into the calibration cavity path, eliminating excess O2 that might otherwise enter the sampling system.

The accuracy of the calibration gas formed using the calibrator is best in the 0-10 PPM range. Since the sensor has linear output through all ranges, the analyzer may be calibrated at one or two ranges above the normal range of operation.

NOTE: For example, if the analyzer is to be used for analysis in the 0–50

PPB range, calibrate the analyzer in the 0–100 PPB or 0–1 PPM range to minimize calibration error. At this level, errors due to mass flow controller calibration, measurement of current from a current source and current leakage are minimized.

To see why, assume the absolute error during calibration on any range is 2 PPB. If the analyzer is calibrated at 25 PPB, 2 PPB error constitutes an 8% error in calibration. However, if the analyzer is calibrated at 80 PPB the calibration error will be only 2.5%.

Sample System

The sample system delivers gases to the O2 sensor from the analyzer rear panel inlet. Depending on the mode of operation (determined by which valves are open or closed), either a sample, span or zero gas is delivered.

Chapter 2Chapter 2

Chapter 2

Chapter 2Chapter 2

The 3060E sample system is designed and fabricated to insure that the O concentration of the gas is not altered (except in the O2 scrubber) as it travels through the sample system.

• Electropolished 316L Stainless Steel Components

To eliminate O2 absorption and desorption from the internal wetted surfaces of the sample system components, the sample system is fabricated from electropolished 316L stainless steel.

• Welding/Metal Gasket-Type Fittings

All of the joints upstream of the O2 sensor are orbitally welded, except for the metal gasket-type compression connections at the O scrubber and mass flow controller. Orbital welding is used in the sample system wherever feasible. Orbital welding fuses the electropolished 316L stainless steel components together, forming a smooth, clean internal (wetted) weld junction and eliminating small spaces around the weld junction where gases can get trapped or absorbed. All of the weld junctions in the entire assembly are purged using an inert gas during welding to ensure that there is no O2 contamination.

Orbital welding is used where practical; otherwise, conventional precision welding is used. For example, conventional precision welding is used to fuse the tubes to the mounting plates. Metal gasket-type compression connections are used at the O2 scrubber and at the mass flow controller to facilitate replacement. The metal gasket-type connection creates an airtight, metal-to-metal seal, eliminating inboard and outboard gas leakage.

• Valves

The analyzer sampling system utilizes three different types of valves. Each valve is selected to prevent O2 contamination of the sample depending on its position and purpose in the circuit.

Air-Actuated Bellows Valves

These valves are normally closed in the sample system. They are used to control the delivery through the sample system of the sample, span or zero gas. The valve bodies are orbitally welded in the system and the valve bonnets make a metal-to-metal seal to the body. This valve system eliminates inboard and outboard gas leakage. The valves are activated (open/closed) by computer-controlled solenoid valves.

The valves have the following basic functions:

PV1: Sample gas to the Ultra Trace sensor. PV2: Zero gas to the Ultra Trace sensor. PV3: Zero gas to the calibrator. PV4: Span gas out of the calibrator. PV5: External span gas to the Ultra Trace sensor. PV6: Sample gas into the scrubber. PV7: Zero gas out of the scrubber. PV8: Sample bypass vent. PV9: Water to the Ultra Trace sensor. PV10: Calibration bypass.

Metering Valve

The metering valve (labeled MV1 on the flow schematic) is used to manually control the sparge rate to the sensor. The body of the metering valve is orbitally welded and the bonnet is sealed to the body with metal O-rings. The manual control knob is located in the sensor compartment.

Solenoid Valves

The solenoid valves control the air flow to the air-activated bellows valves. The solenoid valves are controlled by the microprocessor. When de-energized, the valve outlet is open to ambient air, allowing the air-activated bellows valve to close.

• Oxygen Scrubber

The O2 scrubber is used to remove O2 (down to less than 1 PPB, typically 0.5 PPB) from the sample gas. The scrubbed gas is used for:

Sparging

Electrolyte in the Ultra Trace oxygen sensor is sparged with oxygen-free gas to reduce dissolved oxygen from the electrolyte.

Zero Calibration

The oxygen-free gas is used to electronically offset the background signal of the Ultra Trace sensor. This provides a zero point for the system to measure the oxygen content of the sample gas during analysis.

Span Calibration Using Internal Calibrator

Chapter 2Chapter 2

Chapter 2

Chapter 2Chapter 2

The oxygen-free gas is mixed with oxygen generated in the electrochemical calibrator to produce a span gas with a known oxygen concentration. This provides a span point for the system to measure the oxygen content of the sample during analysis.

NOTE: The standard O2 scrubber has a capacity of 80 cc of pure O2 .

Under normal operating conditions, the scrubber is expected to last several years. The scrubber is installed in the system using metal gasket and VCR type fittings.

The life of the scrubber is approximately 10 years when subjected to an O2 concentration of 10 PPM at a flow rate of 150 cc/min.

• Mass Flow Controller

A mass flow controller is used to control the rate of gas flowing by the sensing electrode of the sensor. The flow controller is located upstream of the sensor. It provides signal input to the electronics in the control module. The flow rate is displayed on the LCD screen and is typically set at 150 cc/min.

• Fittings

The electropolished 316L stainless steel tees, elbows and crosses used in the sampling system are orbitally welded for system integrity. Small size fittings are used to make the sample system compact and to minimize total system internal volume.

Signal Processing Functions

Analog signal processing is accomplished in two plug-in circuit cards operating under control of the microcomputer. One card processes analog input signals and the other processes analog output signals. Digital signal processing is accomplished directly by the microcomputer. All analog signals are converted to digital early in the processing cycle to minimize analog processing and assure maximum system accuracy, since digital processing is much more accurate than analog and immune to many parameters such as drift and aging.

Analog Input Circuit Board

The analog input printed circuit board (PCB) is actually a plug-in module consisting of a main board and a daughter board. Two analog signals are connected to the inputs of this module for processing. They are:

• Ultra Trace Sensor Current Output

• Mass Flow Controller Output

Chapter 2Chapter 2

Chapter 2

Chapter 2Chapter 2

The circuitry on the daughter board converts the Ultra Trace sensor current to a corresponding voltage, provides range control, isolates system grounds, and filters high frequencies from the signal.

The circuitry on the main board processes the filtered output signal from the daughter board and the signal outputs from the flow controller. All signals are eventually connected through an analog multiplexer (electronic switch) to the input of an analog-to-digital converter, where they are converted to digital signals for use by the microcomputer.

This circuit board also contains a voltage measuring circuit to monitor the voltage outputs of the system power supply, and a gas selector switch circuit to adjust the mass flow controller for the background gas selected.

Analog Output Circuit Board

The analog output printed circuit board (PCB) generates the two 0-1 volt and the two 4-20 mA analog signal outputs available on the rear panel of the analyzer. These signals, generated in digital format by the microcomputer, are converted into analog signals by the circuitry on this PCB. The output signals represent the following:

• 0-1V Signal (Oxygen Measurement)

2-12

This output goes from 0 to 1, representing 0 to 100% of the scale that has been set; i.e., 0.6 volt is equal to 60% of the full scale, or 30 PPB when on the 50 PPB scale. It is possible that the signal may go past zero into the negative range up to -0.25, especially if the ana-

lyzer has been zeroed with a gas that contains a significant concentration of O2 (Figure 2-3).

• 0-1V Range Identifier

This 0 to 1 volt output represents each range with a particular voltage as shown in Table 2-1.

• Isolated 4-20 mA Signal (Oxygen Measurement)

This is a 4 to 20 mA output representing 0 to 100% of the scale, with 4 mA equal to 0%, and 20 mA equal to 100% of that range. This output may also range lower than 4 mA, especially if the analyzer has been zeroed with a gas that contains a significant concentration of O2 (Figure 2-5).

Digital Circuit Board

The digital PCB is a general purpose microcomputer used to control all functions of the analyzer. The analog input PCB and the analog output PCB plug directly into connectors located on the digital PCB. In addition to controlling these analog PCBs, the digital board performs the following functions:

1. Provides valve control commands for the sampling system.

2. Processes input from the control panel pushbuttons.

3. Provides signals for the selectable alarms.

4. Processes serial I/O functions (RS-232 data). The following serial interface default parameters are used:

There are two display screens on the front panel of the analyzer:

LCD

This screen is a dot-matrix display located on the control module of the analyzer. It displays all of the menus and commands for the user to control the system and is the user interface for system operations.

LED

This screen is a 7-segment display located on the front panel of the analyzer, above the control module. This screen displays only oxygen concentration, but it is large and bright to allow the operator to read it at a greater distance. A dimmer switch for this display is located on the display PCB behind the front panel.

Temperature control in the oven, which houses the sensor and Faradaic calibrator, is processed by a stand-alone proportional integrative derivative (PID) controller. Input from the resistive thermal device (RTD) sensor located in the oven is used to regulate two 25-watt heaters. Oven temperature is set at 28 ±2°C and should be kept at this temperature during analyzer operation.

The valve control PCB is external to the control module, across the top of the front panel of the analyzer. This PCB contains driver circuitry to activate the solenoid valves. It also contains and controls dual-color LEDs that indicate the actual status of the pneumatic valves (green for OPEN and red for CLOSED). The valve control PCB operates under the control of the system microcomputer.

4. Purge the electrolyte for about one hour.

NOTE: TET/AI recommends that the sensor be purged before adding

electrolyte. This is done by lowering a plastic/Teflon tube (clean and free of any oil/grease and/or particulates) into the sensor through the opening on the top of the stainless steel mounting plate and flushing the sensor with O2-free gas. Add electrolyte into the sensor while flushing the sensor with O2-free gas. This will eliminate the O2 from the sensor before the addition of prepurged electrolyte. This procedure will substantially reduce the downtime associated with clean-up at the first startup of the analyzer.

Figure 3-4.2. Adding Electrolyte to the Ultra Trace Sensor

NOTE: Review the cautions and warnings on the use of electrolyte at

the beginning of this chapter and in the Material Safety Data Sheets.

Avoid spilling electrolyte on the stainless steel plate. If you spill any electrolyte on the stainless steel plate, wipe it up with damp tissue paper. If electrolyte is not completely wiped, a white residue (potassium carbonate, a reaction product of potassium hydroxide and carbon dioxide in air) will appear with time.

As you pour, ensure that no large air bubbles remain trapped inside the sensor. If large bubbles appear, use the syringe to withdraw electrolyte from the sensor until the bubbles disappear. Return the withdrawn electrolyte to the sensor slowly.

4. Add electrolyte until the level reaches about 1 inch above the yellow

level marker on the front of the Ultra Trace sensor body. DO NOT add electrolyte above the green level marker.

5. Remove the cadmium anode from the holder and immediately insert it into the sensor through the opening in the top mounting plate (Figure 3-5). Ensure that the O-ring is attached to the anode assembly.

Faradaic Calibrator

The Faradaic calibrator is located inside the Ultra Trace sensor compartment. The calibrator consists of a stainless steel block with a Teflon liner inside the block and an electrode assembly. In order to use the Faradaic calibrator, you must add electrolyte to the Teflon calibrator liner.

Adding the recommended amount of calibration electrolyte (about 1/2 c c) to the calibrator generally enables you to use the calibrator for about 10 hours. A countdown timer in the upper right-hand corner of the LCD keeps track of the amount of time the calibrator has been used in a hh:mm format. A flashing “C=0:00” on the display indicates that the calibrator needs refilling.

The analyzer is shipped with the calibrator electrode assembly installed. In order to add electrolyte to the calibrator, the electrode assembly must be removed from the calibrator block. To remove the calibrator electrode assembly, use the following procedures:

1. Disconnect the current source connector from the calibrator assembly.

2. Using the wrenches (W68 and W69) provided, unscrew the four bolts from the top of the calibrator assembly (see Figure 3-7).

3. Lift up and remove the calibrator electrode holder. To avoid contaminating the electrodes, do not touch the calibrator wick and avoid contact between the wick and the calibrator block. Place the calibrator electrode holder on a flat surface with the calibrator wick facing upward.

4. Using the 2 cc micro-syringe supplied, add 1/2 cc of the calibration electrolyte to the calibrator housing by lowering the micro-syringe needle into the center of the Teflon liner in the stainless steel block (see Figure 3-8).

Chapter 3Chapter 3

Chapter 3

Chapter 3Chapter 3

CAUTION: Avoid spilling electrolyte on the stainless steel block. If you

spill any electrolyte on the stainless steel block, wipe it up with a damp tissue paper.

If the electrolyte has entered between the Teflon liner and the stainless steel block, remove the electrolyte from the Teflon liner and then remove the Teflon liner by using a clean screw driver pushing against the liner and pulling it up. Clean the inside of the stainless steel block and the outside of the Teflon liner with tissue paper. Insert the Teflon liner in the stainless steel block and carefully refill it with calibration electrolyte.

Do not add more than 1/2 cc electrolyte to the calibrator. If you overfill the calibrator and electrolyte enters the gas manifold, it can damage the Ultra Trace oxygen sensor, the flow controller, and the valves.

5. After adding electrolyte to the calibrator housing, rinse the calibrator wick with distilled water.

6. With the syringe, carefully put a few drops of electrolyte onto the entire wick including the portion under the electrodes and wait until the wick absorbs some of the electrolyte (see Figure 3-9).

Adding Water to the Reservoir

If the analyzer is to be used continuously for on-line gas analysis, then add approximately 800 cc of distilled water to the reservoir. The rate of water addition to the sensor is controlled by the metering valve MV3 located adjacent to the reservoir, below the top cover plate. The valve MV3 is also accessible from the rear of the analyzer.

The water drip rate is set at the factory at 1 drop every 2–4 minutes. This drip rate is close to the rate of evaporation of water from the Ultra Trace sensor. However, if the water drip rate is not proper, the electrolyte level in the Ultra Trace sensor will not be maintained at the desired level (between the yellow and green level markers). A drip rate that is too slow will cause the electrolyte level to drop slowly. If this occurs, open MV3 slightly (1/2 turn) by rotating the valve control knob anticlockwise. See Figure 3-11 for the location of MV3. Repeat this step if necessary.

Chapter 3Chapter 3

Chapter 3

Chapter 3Chapter 3

Figure 3-11. Piping Layout, Water Reservoir and Metering Valves

CAUTION: If you open valve MV3 too wide, an excessive amount of water

will enter the sensor and the output will increase but will slowly return to the original value. With MV3 open too wide, the level detector will open and close more frequently causing output instability. If this occurs, close MV3 slowly until the drip rate is normal. If you experience difficulty in adjusting MV3, you may add prepurged water directly to the sensor through the filler port.

Level Detector and Solenoid Switch

yzyz

erer

The level detector senses when the electrolyte level in the sensor drops, usually as a result of water evaporation. When this occurs, a solenoid valve (valve 9 on the Status Panel) opens and replenishes the lost water at a rate depending on the relative opening of metering valve MV3.

Ocassionally, trapped air between the solenoid valve (valve 9) and the metering valve (MV3) will prevent the automatic addition of water to the sensor even though the level detector is sensing a low electrolyte condition and the solenoid valve is open. In some units, a toggle switch has been installed as shown in Figure 3-6 which when switched off and on several times, causes the solenoid valve (valve 9) to open and close repeatedly and dislodges any trapped gas. In units without this toggle switch, repeated opening and closing of the solenoid valve is accomplished through the software.

For the units with the toggle switch, the switch should be left in the ON position for normal operation. Moving the toggle switch to the OFF position causes the solenoid valve to close. If trapped gas is suspected, alternately opening and closing the solenoid valve by switching the toggle switch off and on several times will create a slight pressure pulse and drive out any trapped pockets of air.

NOTE: The toggle switch must be left in the ON position for normal

operation. If the switch is left in the OFF position, the water replenishing solenoid valve (valve 9) will remain closed regardless of the electrolyte level in the sensor. Opening MV3 will have no effect on the electrolyte level. Instability and damage to the Ultra Trace sensor will eventually result as the electrodes become dry.

Electrical Installation

Electrical Connections

All of the electrical connections originate at the back of the analyzer (see Figure 3-15). The analyzer is shipped with all of the electrical connections intact. There is no assembly or installation required. The four output signal connectors are screw terminals for two wires per output and polarity is noted below each set of terminals. The five alarm circuit connectors are screw terminals for alarm relay contacts which are noted below each set of terminals.

The five selectable alarms provide a set of Form C contacts. The contacts are capable of switching up to 3 amperes at 115 VAC into a resistive load.

The RS-232 port is configured as data terminal equipment (DTE) and uses a 9-pin D connector wired as follows:

Gas Line Connections

All of the gas lines to the system hook up at the back of the unit. See Figure 3-15. All of the fittings are 1/4 " male VCR-type fittings, with the exception of the compressed air inlet fitting. You have been provided with VCR glands, gaskets and female nuts. The glands must be orbitally welded to electro-polished 1/4 " tubing and then connected to the inlet/outlet connections on the instrument. Use 3/4 " and 5/8 " wrenches to connect the gas lines. Insert the gasket (P/N G284) between the fitting and tighten the female and male nuts until finger-tight; then, by holding the male nut with the wrench, tighten the female nut with the second wrench by 1/6 turn.

CAUTION: Do not put any torque on the tubes welded on the sam-

pling system.

Check that each of the lines is hooked up to the correct connection. The lines should be connected in the following order:

1. Span Gas In

If you choose to use a span gas to calibrate the analyzer, connect the span gas tank to the span gas inlet.

Teledyne Electronic Technologies

Analytical Instruments

3-19

Page 46

Model 3060EModel 3060E

Model 3060E

Model 3060EModel 3060E

2. Sparger Vent The sparger vent transports the oxygen-contaminated gas out of the system after it leaves the Ultra Trace sensor. The sparge gas vent is routed through the water reservoir (gas flows above water) to purge out any oxygen in the water reservoir.

3. Sample Gas In Hook up the sample gas to the sample gas inlet. Switch the gas selector on the front panel to the appropriate sample gas coming into the system: N2, Ar, H2 or He. When the sample gas flows through the oxygen scrubber, the sample gas becomes the zero gas and can be used for calibration.

4. Sample Bypass Out The bypass vent allows a part of the sample gas to come out of the sample system without entering the Ultra Trace sensor, decreasing the response and recovery times of the analyzer. The bypass vent is set at 1 liter/minute at the factory. The metering valve MV2 that controls the rate of the bypass vent is located near the rear end of the sampling system. See Figure 3-11. To access this valve, open the top and back covers of the analyzer.

Chapter 3Chapter 3

Chapter 3

Chapter 3Chapter 3

5. Sample/Span Vent The sample/span vent transports the sample or span gas out of the system after exposure to the Ultra Trace sensor.

Caution: The sample/span and sparger vents must be connected to vent

tubes of at least 1/4 in OD, preferably 1/2 in or larger. Using smaller tubing may result in significant backpressure which could force the vent gas to pass through the sensing electrode and cause damage or even rupture the sensing electrode.

6. Air In

The compressed (instrument) air inlet is a 1/4 " tube fitting. Compressed air is used to actuate the pneumatic valves, and is controlled by the solenoid valves, which are in turn controlled by the microprocessor. The inlet air pressure should be between 75 and 80 psig. Pressure lower than 75 psig may not actuate the pneumatic valves, leaving them closed. However, be careful not to exceed 80 psig.

CAUTION: Pressure higher than 100 psig can damage the solenoid

valves.

7. Water Reservoir and Reservoir Drain

The water reservoir supplies water for automatic replenishment of water to the Ultra Trace sensor. Before transporting the analyzer, all water must be drained by opening the reservoir drain.

8. Calibrator Bypass

This outlet is used when purging the Faradaic calibrator, such as after replacing the electrolyte. It prevents a spike from appearing in analyzer output due to contamination with air.

Installation Checklist

After installing the system, confirm the following:

• The sample gas connection to the analyzer sample inlet port is not leaking.

• The sample gas pressure must be between 10 and 30 psig.

• The span gas pressure must be between 10 and 30 psig.

• There are no leaks between the span gas tank and the analyzer span gas inlet port when a span gas is used to calibrate.

• The air supply connection to the analyzer port is not leaking.

• The air supply pressure must be between 75 and 80 psig.

• The vent tubes must be properly installed and should be at least outer diameter. (Tubing with less than 1/4 " O.D. causes backpressure that forces gas to flow through the sensing membrane of the Ultra Trace sensor, generating signal noise.)

CAUTION: Close any valves gently. If valves are over-tightened, the

valve stems can be damaged.

Metering valve MV2 is located near the rear of the sampling system and controls the sample bypass flow rate.

Metering valve MV3 is located near the middle of the right side of the water reservoir and below the analyzer top cover plate and controls the water drip rate to the Ultra Trace sensor. See Figure 3-11.

On some units, a toggle switch has been installed to switch solenoid valve 9 (see Figure 4-2) off and on. This switch is shown in the inset of Figure 3-6. It is used to dislodge any trapped gas in the water replenishing line. Units without the switch have an additional menu in the software labelled RESVR which automatically toggles the solenoid valve.

2. Full/Quick Start Mode Full Start purges the sample, zero, calibrator and span gas lines before the analyzer is used for the first time. Quick Start purges the sampling line after disconnecting and connecting the gas inlet lines, or after the unit has been turned off momentarily. Use Quick Start after the analyzer has been running on a daily basis and the sample/ span gas needs to be disconnected/connected. (To disconnect/ connect gas lines, the analyzer must be in Stand-by mode. See Stand-by mode menu information later in this chapter.)

3. Analyze mode (Calibration/Setup/Range/Stdby) Analyze mode is the normal mode of sample gas analysis. During normal analysis of the sample gas, other modes available from the Analyze mode are:

a. Calibration mode:

Allows you to set the analyzer zero and span.

c. Range:

Allows you to set the range manually or use the AutoRanging feature.

d. Stand-by (shutdown) mode:

Keeps the analyzer ready for operation when:

• no gas is flowing through the system

• the sample/span gas line is being connected or disconnected

• proceeding through normal shutdown of the analyzer.

4. High Current Output mode: Closes all valves to protect the Ultra Trace sensor and preserve the oxygen scrubber when concentrations of oxygen higher than 30 PPM are detected for longer than two minutes. (This mode is activated only when the analyzer is in the Analyze mode). Pressing buttons in certain sequences allows you to set modes of operation. The system’s electronics subsequently operate the correct valves depending on the options that you choose. The choices are displayed on the LCD screen and vary depending on the mode.

Sensor Compartment Temperature Controller

The Ultra Trace sensor is housed in an insulated compartment oven located at the front of the analyzer. See Figure 4-3. The temperature of the sensor housing is controlled at 28 ±2°C by a proportional integrative derivative (PID) controller located behind the rear sample system cover plate. Input from a resistive thermal device (RTD) located in the sensor housing is used to regulate two 25 W heaters. The temperature controller is shown in Figure 3-11 and the heaters are shown in Figure 4-3.

Ultra Trace Sensor Electrolyte Temperature

The temperature of the Ultra Trace sensor is continuously monitored and displayed in the upper right hand corner of the LCD screen by an input from a thermistor inserted into the sensor from the Ultra Trace sensor top mounting plate (see Figure 2.2). The nominal value of electrolyte temperature is between 25-31°C (after the oven temperature has stabilized). If the displayed temperature is outside this limit and the ambient temperature is below 32° C, replace the thermistor.

13. After verification of the above step, turn the power ON.

Modes of Operation

Cold Start

The very first time you turn power on, the display will indicate model number, Company name, software version and COLD START.

NOTE: When you power up the instrument for the first time and the display

does not indicate COLD START, turn the power off, wait 10 seconds and then turn the power back on while holding down the red key on the Control Module. This will force a COLD START.

With COLD START, all parameters, such as calibration and alarms, revert to factory default values. With the preset default calibration values, the sample gas analysis readings may be 20-60 % off the true values. Therefore, it is essential to perform span and zero calibration prior to using the analyzer for sample gas analysis. A cold start enables you to:

• Purge the electrolyte in the Ultra Trace sensor and calibrator and the entire sample system.

• Set up calibration parameters for the analyzer.

• Set the alarms.

• Set a three-digit authorization code.

NOTE: Once an authorization code has been entered, subsequent alarm

setting changes will require entry of the authorized code.

the system will continue to step 26.

• Open MV1 slowly until you see a fine stream of nitrogen bubbles emerging from the porous frit mounted at the bottom of the Ultra Trace sensor. There is no flow sensor on the electrolyte sparging vent line to monitor flow. The rate of sparging should be such that fine nitrogen bubbles leave the electrolyte without causing significant turbulence.

• Initially, the sparger may be set to a higher value however, when the oxygen reading falls below 1 PPM you should lower the sparging rate. The signal noise level will depend on the electrolyte sparging rate. Electrolyte sparging should never be completely stopped. If the sparging is completely stopped, air may diffuse back into the Ultra Trace sensor through the sparger vent line and interfere with measurements producing very erratic output. The rate of sparging at 100 to 50 PPB ranges should be minimal and adjusted according to the signal noise levels.

4-18

• Typical expected noise level at the 50 PPB range is 0.5–1 PPB. However, the noise level at the first start-up may be 1–2 PPB and may show some spiking due to the presence of dissolved oxygen in the electrolyte. The noise level, magnitude, and frequency of the spikes will diminish with time as the dissolved oxygen is removed by sparging.

After initial start-up, the analyzer automatically enters the Analyze mode. In the Analyze mode, the sample gas is constantly monitored while four menus are offered: Calibration, Setup, Range, and Stand-by. You can enter any of these menus from the Analyze mode, and return to the Analyze mode once you are done.

Before analyzing a sample gas, the analyzer must be first spanned and then zeroed. During span calibration, a gas with a known concentration of oxygen is sent to the Ultra Trace sensor and a reading is kept in computer memory. The span of the analyzer is automatically adjusted to produce a signal readout that is equivalent to the known concentration of oxygen supplied in the span gas. The analyzer can be span calibrated with either the Faradaic calibrator in the system or a span gas of your choice. During the zero calibration process, the analyzer transports the sample gas through the built-in scrubber, which removes all of the oxygen in the gas and produces the zero gas. The zero gas is then sent to the Ultra Trace sensor, where the reading is recorded into computer memory.

Both span and zero functions can be set to run automatically at specified intervals in the Setup mode.

Conditioning the Ultra Trace Sensor

Raw output from the Ultra Trace sensor is typically between 16–18 µΑ /PPM of oxygen. If the output is below 6µA/PPM, the microprocessor will send an error message "CELL TO WEAK". On the other hand, if the output is above 18mA /PPM, the microprocessor will send an error message "CELL TO STRONG". In either case, the microprocessor will be unable to adjust the span sensitivity.

The Ultra Trace sensor is qualified at the factory by measuring its raw output. However, when the analyzer is shipped to the user, the sensing element of the Ultra Trace sensor becomes dry and the output may become lower than the acceptable limit. Therefore, when the analyzer is placed into service for the very first time, it may become necessary to condition/activate the Ultra Trace sensor before attempting span and zero calibrations. This is done by introducing a span gas between 5–9 PPM (either from an external source or generated by the builtin Faradaic calibrator) until the sensor output is at least 1/3 of the span gas.

CAUTION: If the internal Faradaic calibrator is used to condition the

Ultra Trace sensor, the calibrator must be refilled with calibration electrolyte after 10 hours of operation (see Chapter 3). Failure to refill the calibrator will result in a CURRENT FAILURE error message. To refill the calibrator with calibration electrolyte, return to the Analyze mode. (From the Calibration mode, press ESC.) After refilling the calibrator, replace the electrode assembly and return to the Calibration mode.

To condition the Ultra Trace sensor, go to the Calibration mode and select either the GAS or INTERNAL calibration mode (see Span Calibration on the next page). Select MANUAL SETTLING. Stay in the Calibration mode (do not press ACK in step 7 during conditioning with an external gas or step 10 during span calibration with internal calibrator). The output will increase slowly with time, and will eventually reach a steady state value. This is a result of electrolyte slowly wetting the catalyst in the sensing electrode. After the catalyst has been completely wetted, the output will stabilize.

Chapter 4Chapter 4

Chapter 4

Chapter 4Chapter 4

After conditioning, the signal output will reach at least one-third of the preset span value. For example, a 9 PPM span gas used during conditioning will result in output of at least 3 PPM after conditioning. Once the output has reached 1/3 of the span value, press ACK to adjust the analyzer span.

CAUTION: Failure to condition the Ultra Trace sensor may result in a

"CELL TOO WEAK" error message. To correct this, condition the sensor again and recalibrate the analyzer. If the output after conditioning for a maximum period of 48 hours does not reach 1/3 of the span value, replace the sensor.

NOTE: It is recommended that the analyzer be spanned before the

background signal is offset.

NOTE: With the factory preset Ultra Trace span sensitivity (for details, see

Cold Start mode), the Ultra Trace sensor signal must be at least 1/

3 of the selected span gas value to adjust the span sensitivity to a new

value. For example, if you use a 9.00 PPM span gas, the analyzer should display at least 3 PPM in order to adjust the span to 9.00 PPM. If the signal is less than 1/3 of the selected span, stay in the calibration mode until the signal is > 1/3 of the selected span. For the first time the analyzer is switched to a span gas, the signal output will slowly increase due to the slow wetting of the catalyst, and after some time, reach a steady value. This is typical behavior in a gas-diffusion electrode. (See Section 4.3.6.1 for details).

A span gas of any concentration (less than 10 PPM) can be used to calibrate the analyzer. When you calibrate the analyzer at 10 PPM for the first time, or after the Ultra Trace sensor has been exposed to zero gas for several weeks, the signal output during calibration will slowly rise. The 90% response time in the Analyze mode is 55–75 seconds. The last 10% response may take up to 30 minutes to stabilize.

The internal calibrator is designed to generate a calibration gas of up to 8 PPM. TBE recommends calibrating with a span gas of at least 80 PPB on the 100 PPB range. Calibrating the analyzer with low PPB oxygen generated by the internal calibrator may require up to 2 hours to stabilize. However, calibration at 500–700 PPB may be completed within 20–30 minutes. The recovery to zero line after calibration at 500–700 PPB is slower than that with 80 PPB, but this slow recovery easily offsets the longer span stabilization at 80 PPB. Therefore, it is highly recommended that you calibrate the analyzer at 500–700 PPB when using the internal calibrator to achieve the maximum accuracy.

reading has settled and is less than 5–10% of the full scale of calibration range.

If the output does not fall below 5–10 % of full scale, return to the Analyze mode, wait for 30 minutes, and then return to the Calibration mode. During the waiting period, the difference in the partial pressure of oxygen in the calibration electrolyte and the zero gas above the electrolyte forces the dissolved oxygen out of the electrolyte. Remaining in the Analyze mode conserves the electrolyte in the calibrator. Repeat the procedure if necessary.

Note: With the factory preset Ultra Trace span sensitivity (for details, see

Cold Start mode), the Ultra Trace sensor signal must be at least 1/3 of the selected span gas value to adjust the span sensitivity to a new value. For example, if you use a 9.00 PPM span gas, the analyzer should display at least 3 PPM in order to adjust the span to 9.00 PPM. If the signal is less than 1/3 of the selected span, stay in the calibration mode until the signal is > 1/3 of the selected span. For the first time the analyzer is switched to a span gas, the signal output will slowly increase due to the slow wetting of the catalyst, and after some time, reach a steady value. This is typical behavior in a gas-diffusion electrode.

When the analyzer is span calibrated with less than 1 PPM oxygen, make sure that background signal is not greater than 100 PPB. If you attempt to span the analyzer with a higher background level, the sensor output, which will be the sum of the background and span gas signals, may go out of the range acceptible to the microprocessor and an error message "CELL TOO STRONG" will be displayed. Press the START key to reset the analyzer to the factory settings.

It may take up to 30 minutes for the oxygen level to reach a stable value. With internal calibration, the noise level will be close to 1–2% of full scale. However, if too much electrolyte is added, or the calibrator electrodes are covered with electrolyte, the noise level may be higher and/or the signal may show some spiking. The amplitude of the spikes is more pronounced at concentrations above 1 PPM. If this occurs, stay in the Calibration mode. The electrolyte level in the calibrator will slowly decrease, and the noise level will decrease accordingly. Do not open the calibrator and attempt to remove excess electrolyte from the calibrator. If the amplitude of the spikes does not decrease, press ACK at the base line of the calibration curve to minimize error in calibration. See Figure 4-7.

It is recommended that you do not generate more than 6 ppm oxygen from the internal calibrator for calibration. When monitoring PPB levels of oxygen, the analyzer should be spanned around 500 PPB to achieve optimum performance.

Important Notes on Zero and Span Calibration

with oxygen concentrations in the PPB range, the analyzer is programmed not to offset any background signal exceeding a chosen maximum value. If you attempt to offset a background signal higher than that value, the system displays the error message CANNOT ZERO. BACKGROUND LEVEL MORE THAN THE RECOMMENDED VALUE. The analyzer will wait until the background signal drops below that value.

zero readings, however, are usually completed in 5–30 minutes.

PPB oxygen. During initial start-up, the background signal may be greater than 60 PPB. The background signal level decreases slowly as dissolved oxygen is gradually removed from the electrolyte with continued sparging.

erer

iv. If you adjust the zero when the signal is greater than 60 PPB, the zero line

may drift slowly to a negative value. It is recommended that you adjust the zero frequently during the first 3–4 weeks of operation, preferably once every day during the first week and then once every two days for the second and third week. After the third week, adjust the zero once per week.

v. The value of the corrected background signal is stored in the computer

memory. In the Analyze mode, the value displayed is always corrected for the background signal. However, when you enter the Zero mode, the previously corrected background plus the current background signal will be displayed. For example, assume that you offset a background signal of 60 ppb and then return to the analyze mode. After a few days, you are reading the oxygen concentration in the analyze mode as 5 ppb. You then decide to rezero the analyzer. As soon as you enter the zero mode, the analyzer will read 65 ppb and then will settle slowly to a new zero line (usually within 5–10 minutes). This is to ensure that you do not correct the background signal more than the recommended value at any time. See Figure 4-8.

vi. The maximum raw background signal that can be offset is –10 to 150 PPB

equivalent, and is dependent on the signal output per PPM of the Ultra Trace sensor, which may vary during operation.

vii. The span of the analyzer is very stable and does not require frequent span

calibration. Therefore, TET/AI recommends that you span calibrate the analyzer at least once each week during the first four weeks and then once every two weeks during the next eight weeks. After this time, the analyzer should be calibrated once a month. TET/AI recommends calibrating the analyzer in the 0–1 or 0–10 PPM range with a typical span gas value of 500–700 PPB.

• High/Low indicates whether the level is a high- or low-threshold.

• Latching option YES means that the alarm will continue to ring

after being triggered by an alarm status, even though the oxygen has returned to acceptable levels. The ALRMR button on the keyboard in the Analyze mode menu must be pressed to end the alarm.

• Defeat option YES renders the alarm inoperative.

Setup: Auto Settling

The Auto Settling setup mode allows the user to set parameters (Period and Slope) for the automatic calibration cycles to achieve optimum instrument accuracy based on the user's needs.

The Zero and Span calibration modes involve switching between a sample gas and a calibration gas. Ideally, this switching would produce an instantaneous step function in the output as the instrument goes from Analyze mode at some oxygen concentration to calibration mode (Zero or Span) at a distinctly different concentration. In the real world, a transient state is produced where the oxygen level changes rapidly at first and then settles slowly to equilibrium. Calibration error can arise if the system takes on a zero or span value before the oxygen level stabilizes.

The Auto Settling function looks at the rate at which the oxygen concentration is changing after entering a calibration mode. It compares this rate with a default or operator set value (SLOPE) and sets the zero or span value when the slopes are equal. The rate of change of oxygen concentration (slope of the concentration vs time curve) is determined by averaging the concentration over some specified PERIOD. This period is set at 5 minutes at the factory but can be changed by the user during the Auto Settling setup.

Chapter 4Chapter 4

Chapter 4

Chapter 4Chapter 4

During auto settling, the factory-set period of 5 minutes can be the optimum trade-off for accuracy versus time. For example, setting the analyzer for a shorter settling period, such as 1 minute, takes less time; however, calibration is also less accurate. On the other hand, a 10 minute settling period provides for more accuracy, but takes longer to calibrate.

In setting zero slope and span slope settling parameters, use the preset slope values to achieve the best accuracy-to-time calibration. These parameters determine the accuracy of zero and span. While a smaller value will give the best accuracy, a smaller slope value will require a much longer stabilization time. See the accompanying graphs shown in Figures 4-9, 4-10 and 4-11.
