1.2 Anatel® PAT700 analyzer overview

The Anatel® PAT700 analyzer provides TOC analysis for pure and ultra-pure water processing.

The PAT700 oxidizes a water sample to determine the TOC in the sample. The analyzer traps a sample in the analysis cell, exposes the sample to ultraviolet (UV) light, and monitors changes in temperature and conductivity until the sample has completely oxidized. Once full oxidation has occurred, the analyzer reports TOC, temperature, conductivity, and the oxidation curve. The PAT700 incorporates the OASIS™ onboard, automated standards introduction system that simplifies analyzer performance testing using standards bottles tagged with RFID technology.

A touch-screen interface provides access to all analyzer functions. The user interface consists of a home screen from which all user operation initiates. The home screen displays the current status of the analyzer, TOC level, and environmental data. The software can display data in a number of user-selected formats, including TOC, compensated and uncompensa ted conductivity, and temperature in engineering units, with graphical representations of the data. Compliance with 21 CFR Part 11 is ensured with password protection and an audit trail of all

• You can interact with the analyzer remotely, including downloading data records, by querying the analyzer through an RS-232 communications port.

• You can communicate with the analyzer using Modbus

protocol via the Ethernet port. Alternatively, the user may connect a memory stick to the unit and download the contents of the data buffer and bottle analysis reports.

• You can print data on a remote printer via the RS-232 serial port.

• Printing may be done automatically or on demand through an RS-232 port to a serial printer.

1.3 RFID technology

The Aantel PAT700 on-line TOC analyzer Onboard Automated Standards Introduction System (OASIS™) employs Radio Frequency Identification (RFID) technology, a registered radio frequency device. The RFID system in the PAT700 operates over a very short distance to eliminate any interference with other wireless communications.

The term RFID describes a system that transmits data wirelessly, using radio waves, over a very short distance. An RFID system is comprised of a “tag” and a “reader/writer”. In the PAT700 analyzer, the tag is attached to the standards bottles used in calibrations (conductivity and TOC), validations, and system suitability tests. The RFID tag consists of a microchip attached to a radio antenna mounted on a substrate. The RFID tag is attached to the bottom of the standards bottle. The microchip contains data about the standard contained in the bottle. The PAT700 OASIS system contains four RFID reader/writers permanently mounted inside the analyzer that align with the bottle RFID tags when the bottles are fully loaded in the analyzer. The reader/writer retrieves the data stored on the RFID tags located on the bottom of the standards bottles. The RFID reader/writers have antennas that emit radio waves and receive signals back from the tags on the standards bottles. The information provided from the tag includes the identity of the standard, the standard’s concentration, date of expiration and other pertinent data.

Operator Manual Anatel

WGM - 26 July 2007 - Edition 01-d4

PAT700 Total Organic Carbon Analyzer – Before You Begin Page 3

The reader/writer takes the data received from the tag and passes the information in digital form to the PAT700 processor. The RFID system in the PAT700 can read and write to the RFID tags attached to the standards bottle. The writing feature allows the PAT700 to write data to the bottles showing that the bottle has been used and provides for writing of data for the exclusive excursion sampling feature.

The RFID system in the PAT700 does not require any user intervention to operate. The system operates automatically when bottle tests are performed. The system automatically turns on and off to read and write data only when necessary. When enabled, the radio frequency modulation emitted from the antennas is fixed at 13.56 Mhz. There are no user serviceable parts associated with the RFID system. The RFID reader/writer board assembly should only be serviced by a Hach Ultra certified service representative.

Since the RFID labels on the standards bottles contain the data necessary for each standard, the labels must not be removed from the bottle. Without the label, the RFID reader/writer has no data to read and will not operate as intended.

1.8 Definitions of terms

The following terms are used throughout this manual:

Conductivity. A measure of the ability to conduct current through water. Conductivity, very

low with high-purity deionized water, is the reciprocal of resistivity and is measured in microsiemens per centimeter (μS/cm).

Megohm (M). A measurement of 1,000,000 ohms. Microsiemens (μS). A unit of conductance in the metric system equivalent to one millionth of

-6

an ampere per volt (1 µS = 1 x 10

A/V).

Normalize. To make conform to a standard. In this case, the user performs calculations on

the raw data to produce a result in a standard unit of measure.

Organic. Organic chemicals, including carbon atoms in complex molecules, but not including

carbonate (CO

, HCO3, CO3) or cyanide (CN) related compounds. Oxygen is very common

in organics, and they almost always include hydrogen.

Oxidation. The loss of electrons by a chemical species, typically with oxygen. Organic

carbon, for example, oxidizes to carbon dioxide and water.

Parts per billion (ppb). A term used to report trace chemical analyses. It refers to the

concentration of the element or compound present within one billion parts of water. One microgram per liter (µg/L) is equal to 1 ppb).

Resistivity. Resistance, measured in megohmcentimeters (M-cm), to the flow of electrical

current through high-purity water. Resistivity is a means of continuously measuring the purity of the water and is the reciprocal of conductivity.

Temperature compensation. Conductivity and resistivity measurements normalized to

25 °C (77 °F) for reporting purposes. Normalized conductivity and resistivity measurements reflect the values that would be reported at a sample temperature of 25 °C (77 °F) using a model based on sodium chloride in water. Conductivity and resistivity of electric current in water depend on the temperature of the water. The lower the temperature, the lower the conductivity and the higher the resistivity.

Mounting general considerations

Follow these guidelines when installing the analyzer:

• Locate the analyzer where it is accessible for operation, service and calibration.

• Minimize the distance between the water system sample point and the analyzer to allow for representative sampling.

• Locate the analyzer where the ambient temperature remains between 15 and 35 °C (59 and 95 °F).

• The transmitter mounting bracket is installed independently from the analyzer. Once mounted, the analyzer hooks on the mounting bracket and locks into place with twist latches.

• Mount the transmitter mounting bracket to a stable, flat surface or dual instrument poles.

• The front of the analyzer requires 12 inches (30.48 cm) of clearance to allow the doors to open completely.

• The analyzer is available with ¾-inch conduit openings or quick-connect fittings for power and I/O wiring. If conduit is used, install fittings that ensure a complete seal with the openings and are properly sealed to keep the analyzer electronics compartment watertight.

Mounting to a wall

Follow these guidelines and refer to Figure 2-1 and Figure 2-3 to mount the transmitter to a wall or other flat, rigid surface:

• Use 5/16-inch (8 mm) diameter screws or bolts and nuts to mount the analyzer to a wall or other flat, rigid surface. Use hardware that can withstand the process environment. Hach Ultra does not supply hardware.

• To minimize stress on the analyzer mounting bracket, secure all mounting bolts to the same structure, which should be flat and should not vibrate or move excessively. Do not secure bolts to separate girders, beams, or wall studs, which can move independently.

WGM - 26 July 2007 - Edition 01-d4

Data read commands

The data read functions return multiple values, the string terminated with a <cr><lf>. If the analyzer is in an operational mode that does not generate a TOC result (modes 6

through 12), the TOC, TOC alarm percentage, TOC trend, profile (curve) type, and oxidation time are not returned.

Data normally are returned only in response to issuance of the RD or RE commands. When collecting data with a serial communications program such as Windows 95 Hyperterminal, however, it is more convenient to have the data displayed automatically. This can be done using the SA command, which then displays data whenever they are reported.

Chapter 3 Startup

3.1 Startup sequence

The analyzer goes through the following sequence on power up:

1) Splash window: The splash window appears at startup while the system checks

for the FAT driver, copies files, and launches the application.

2) Verify lamp monitor: After the system has initialized, it verifies that the lamp

monitor works by turning on the main lamp and ensuring a voltage is returned. The analyzer needs to enable the lamp to warm up for a few seconds to ensure a valid result.

3) Sample bottle check: The system checks to see if the bottles loaded in the sample

cartridge match the last known configuration. If the bottles contain RFID tags, the analyzer reads the tags and compare them against the information stored in the settings. If the RFID tag doesn’t match what’s stored in the settings, the settings is updated with the new information and a warning is generated. If the settings list a non-RFID tagged bottle in one of the bottle positions and an RFID tag cannot be detected in that position, the analyzer assumes the bottle is still present.

4) Start sampling: If the analyzer is configured to one of the Auto TOC modes, it

starts sampling after it has powered up.

5) Print header: After the system has started up, it prints a header that tells when the

system was rebooted, and its condition. It prints the column header for the normal operation mode.

Chapter 4 Run modes

4.1 The analysis cycle

An analysis cycle is comprised of a flush of the analysis cell, oxidation, and idle time (if the cycle time is greater than the combined flush and oxidation time).

Oxidation time varies based on the amount of total organic carbon in the sample. Flush time is fixed and idle time varies to allow for varying analysis cycle time. See Figure 4-1.

Idle time occurs only after an online TOC analysis has been completed and only if the elapsed time has not exceeded the value for cycle time.

• If conductivity was selected during idle, the analyzer reports conductivity during the idle time.

• If no conductivity was selected, the analyzer verifies the lamp is off and opens the bypass valve.

Page 34 Run modes – PAT700 Total Organic Carbon Analyzer

CAUTION

Using the sample pump on a pressurized system could damage the pump.

Do not use the pump on a pressurized system.

In online TOC mode, the cell valve opens to flush the cell.

• If you are sampling from a zero pressure system, you need to enable the pump option to draw water into the cell. In this case, the pump valve must be opened and the pump started for every action that requires drawing water through the cell. The analyzer continues to flush until the elapsed time is equal to the time value that has been set in the setup dialog box. The cell valve is then closed to capture the sample.

• The analysis is started and conductivity and temperature readings are fed into the TOC algorithm. Conductivity is monitored until oxidation is complete.

• When oxidation is complete, the analyzer reports the results to the home screen and the printer if connected. It then checks to see if the elapsed time is greater than or equal to the value for cycle time in settings. If it is, the next online TOC analysis is started. Otherwise, it enters the idle mode.

4.2 Conductivity mode

Figure 4-2 Conductivity mode

In conductivity mode, the analyzer starts by verifying the lamp is off and the cell valve is open to flush the cell. The analyzer reports the current readings for conductivity and temperature to the main display every time a new value is available. The reported value is an average of the data for over the last two seconds. The average reading will also be sent to the printer, based on the printout settings, and the data log.

Standby

In standby, the analyzer verifies the lamp is off and all the valves are open. Standby mode must be terminated by switching to another mode.

Offline

In offline mode, the analyzer verifies the lamp is off and the valves are closed.

4.3 Clean

Figure 4-3 Clean mode

In clean mode, the analyzer starts by setting the elapsed time to 0, opening the cell valve to flush the cell, and turning the lamp on. If timed operation was selected for this mode, the analyzer will display a countdown timer on the dialog box. Otherwise, the elapsed time is displayed. A stop icon will also be displayed on this dialog box to enable you to terminate the operation. The analyzer will remain in this state until the countdown timer reaches 0, you manually stops the operation, or the analyzer is switched to another mode by sch edule or by digital control.

Chapter 6 Bottle mode

6.1 Introduction to bottle mode

The PAT700 Onboard Automated Standards Introduction System (OASIS™) is used for performing standards tests, grab sampling, and excursion sampling. Through the bottle mode, various bottle test functions can be selected. The OASIS is automated through the use of RFID technology (see RFID technology, page 2). When standards bottles with RFID tags are installed in the system, the analyzer uses RFID technology to read and transmit data about the standards to the analyzer. This system eliminates the need for manual data entry.

Although equipped to perform automatically using RFID tagged standards, you may also use bottles without RFID tags by manually entering the standards data when prompted by the analyzer.

Four functions are available under bottle mode: run standards, grab sample, excursion mode , and unload bottles.

6.2 Bottle mode dialog box

The bottle mode dialog box enables you to perform actions using the bottles in the sample cartridge. You may run calibrations, validations, or system suitability tests, analyze samples from a bottle, install an excursion bottle to capture a sample when a TOC measurement exceeds an alarm limit, or schedule tests to be run. See Figure 6-1.

Instructions label instructs you to install the resistor and touch the start test icon. Start test icon reads the value of the resistor. The analyzer must latch the measurement

circuit relays to read the verification resistor. Once the analyzer has read the resistor value, the relays must be unlatched to prevent damage to the circuit. The analyzer then converts this value to conductivity by taking the inverse of the resistance and multiplying it by the cell constant. This value is then compared to the expected value, assuming a 61.9 Kohm resistor. If the measured value is less than or equal to ±0.1 µS/cm of the expected value, the test passes and the next icon is enabled. Otherwise, you are notified and must cancel the calibration.
