1. General Information

This user guide covers the operation, maintenance and troubleshooting for the WE430 Hydrazine

analyzer, which o󰀨ers unmatched reliability in analyzing oxygen scavengers in feedwater, boiler

water or at the economizer inlet.

n Introduction

Analyzer the oxygen scavenger content at points in the steam/water circuit where dissolved oxygen control is critical. Residual oxygen scavengers must be carefully monitored to prevent costly overdosing, yet allow enough of the reductant in the system for metal passivation.

Excess levels of certain oxygen scavengers decompose into ammonia, which increases system

alkalinity. E󰀩cient control of oxygen scavengers depends on maintaining a predetermined safety zone. The WE430 Hydrazine analyzer optimizes the uidic design with the sensing technology

to provide accurate and precise results with an almost instantaneous indication of oxygen scavenger concentration changes.

The WE430 Hydrazine analyzer meets all of the criteria for accurate and dependable oxygen scavenger monitoring and more. The WE430 analyzer incorporates innovative technologies that include:

• Premium electrodes

• Marquee help screen

• Pump-less reagent addition and dynamic calibration system

1-1

l Markets

n Application Modes

The versatility of the WE430 Hydrazine analyzer allows the operator to set the analyzer to read hydrazine, depending on the oxygen scavenger to be measured. Refer to Section 3.1, Use of the Setup Mode for instructions on how to set the analyzer to read hydrazine.

l Hydrazine Application

Hydrazine Measuring Range: 0 ppb to 200 ppb as hydrazine

In high pressure boiler systems, hydrazine is added to react with dissolved oxygen present in the system and a small amount of residual hydrazine is left behind. The residual hydrazine ensures that small amounts of dissolved oxygen that enters the system through leakage will be removed. Residual hydrazine should be carefully monitored to prevent costly overdosing.

Excess hydrazine may also decompose into ammonia, which increases sample alkalinity and

attacks copper alloy components. E󰀩cient control of hydrazine depends on maintaining a

predetermined safety zone – typically 10 to 50 ppb.

1.1 Principles of Operation

The sample enters the WE430 Hydrazine analyzer and passes through the inlet valve, bypass/

needle valve, inlet lter, pressure regulator, ow meter and into the restrictor tubing. The sample then passes through the uid connector block into a reagent bottle and through a di󰀨usion tubing

assembly where pH adjustment takes place and iodine is added. The pH-adjusted sample then

ows back through the connector block into the reagent mixing loop where the oxygen scavenger

in the sample mixes with iodine reagent to form iodide. The sample then passes the iodide

electrode, reference electrode and temperature probe and ows into an atmospheric drain via the

diverter valve.

Where: OS

= oxygen scavenger reduced

OSox = oxygen scavenger oxidized

The iodide sensing electrode responds logarithmically to changes in the resulting iodide ion concentration. This response is described by the Nernst equation:

E = Eo + 2.3 (RT/nF) log (C/C

iso

)

Where:

E = measured electrode potential, mV Eo = potential, when C equals C

E0 default: 44 mV

Low limit of E0: - 50 mV

High limit of E0: + 150 mV

Slope default: - 64.0 mV/decade

Slope range: - 75.0 mV/decade to - 40.0 mV/decade

IM 12Y18A03-01EN 1st Edition : Oct. 04, 2019-00

<1. General Information>

The above equation indicates that the measured potential varies with both temperature and

the concentration of the ion of the interest. In order to eliminate error caused by uctuations in

sample temperature, the WE430 microprocessor constantly updates temperature corrections from data supplied by the ATC probe.

From the Nernst equation, the theoretical response of a iodide ion selective electrode to a tenfold change in concentration at 25 °C is -59.16 mV. This is referred to as the electrode slope (S). Most electrodes, however, do not exhibit a theoretical slope. Therefore, the analyzer is calibrated to determine its actual value. Two standards are used to provide information necessary for the microprocessor to compute the actual slope and E0 for use during sample analysis.

Acid is added to the sample to prevent a competing reaction from occurring:

3I2 + H2O → 5I- + IO

Maintaining acidic conditions prevents the release of iodide which would cause high apparent reductant readings.

The pH adjustment and iodine addition are accomplished by the patented passive-di󰀨usion

process wherein the sample passes through a length of tubing in the reagent bottle that contains

the acid reagent and iodine. The reagent and iodine di󰀨use through the tube wall and mix with

the sample. This passive method eliminates sample contamination problems due to reagent

contamination and makes the uid handling apparatus simple and reliable.

1.2 Principles of Calibration

1-4

Calibration procedures for analytical instruments are important and must be performed carefully. The WE430 Hydrazine analyzer uses a dynamic two point calibration that utilizes advanced electrode technology in combination with a dynamic calibrator.

1.2.1 Dynamic Two Point Calibration (DYN)

The dynamic two point calibration procedure provides maximum calibration accuracy and requires the use of the dynamic calibrator. In addition to calculating the Eo value of the electrode,

as is done in an o󰀪ine calibration procedure, this procedure determines electrode slope. To perform a dynamic two point calibration, the WE430 analyzer is rst connected to a reductantfree sample stream. An appropriate diluted standard is prepared and then a syringe is lled

with the diluted standard and mounted on the calibrator. The calibrator is then mounted near the analyzer and the syringe tubing is connected to the standard injection port. By adjusting the

calibrator pump settings, two di󰀨erent ow rates produce two known standards that are diluted

into the sample background. By pressing the appropriate keys on the analyzer when prompted, the analyzer’s microprocessor completes the calibration. After allowing approximately 30 minutes

for the calibration solution to be ushed from the system, the WE430 analyzer can begin sample

measurement again.

1.2.2 O󰀪ine Calibration

In addition to a dynamic two point calibration, an o󰀪ine calibration can be performed with

some oxygen scavengers. Since the oxygen scavenger concentration in feedwater is normally

controlled over a rather narrow range, usually an o󰀪ine calibration procedure is su󰀩cient to provide accurate results. The o󰀪ine calibration procedure has the advantage of being quick and

easy to perform. If sample reductant concentrations are expected to vary widely from day to day

or if online verication of analyzer readings is desired, a dynamic two point calibration should be

performed.

The o󰀪ine calibration feature of the WE430 analyzer allows the operator to adjust the analyzer to

values determined by alternate methods used in their laboratory such as a standard colorimetric method.

IM 12Y18A03-01EN 1st Edition : Oct. 04, 2019-00

<1. General Information>

The o󰀪ine calibration is essentially a one point calibration. To perform an o󰀪ine calibration, a

sample is taken from the bypass of the analyzer; the sample concentration value is stored in memory; the sample is analyzed by an alternate method of choice; the previously stored reading is adjusted to the lab method result; and the analyzer is then returned to the analysis mode. The

term “o󰀪ine calibration” refers only to the fact that a sample from WE430 analyzer bypass is taken “o󰀪ine” for laboratory analysis; in fact, no downtime is experienced during the procedure

and the analyzer remains online throughout.

WARNING

Be sure to read and observe the following requirements.

l Air Pump Shutdown

WARNING

Turn o󰀨 the air pump prior to removing the reference electrode lling solution bottle. If the air pump is left on, it will spatter lling solution as the bottle is removed.

1. To access air pump, press .

2. Press / to scroll though parameters until TEST appears in marquee window.

3. Press to access the TEST menu.

4. Press / to scroll through the TEST menu until AIr appears in the main display.

5. Press .

6. Press / to toggle between On and OFF settings for the air pump power. Select the OFF setting. Changing the air pump setting to On or OFF will be indicated by a click sound.

7. Press to accept the setting and return to the TEST menu.

8. Press to return to the measure mode.

l Analyzer Shutdown

1. Shut o󰀨 sample ow prior to the analyzer inlet. Refer to Chapter 4, Flow Cell Operation.

2. Disconnect the power. Refer to Section 2.3, Wiring the Analyzer.

3. Drain the ow cell.

4. Remove the reagent bottle and store it in a well-ventilated area such as a laboratory fume hood.

5. Carefully pull the iodide and reference electrodes out of the top of the ow cell and let them

hang by their connectors.

IM 12Y18A03-01EN 1st Edition : Oct. 04, 2019-00

<3. Analyzer Operation>

6. Locate the protective cap from reference electrode kit and place it on the base of the reference electrode to prevent it from drying out.

n Start-Up

1. Replace the di󰀨usion tubing if the sample ow was o󰀨 for more than a few days. Tubing

becomes brittle with long-term exposure to the reagent. If the age of the reagent is not known, replace it and note the date in the maintenance records. Re-install the reagent bottle on the analyzer.

2. Restore sample ow to the analyzer. If necessary, adjust the pressure and ow rate through

the analyzer to 40 mL/min.

3. Remove the protective cap from the reference electrode. Re-install the electrodes on the analyzer. Be careful not to disconnect the reservoir tubing from the reference electrode sidearm.

4. Allow the analyzer to stabilize for approximately 1 hour and then recalibrate. Refer to Section 4.4, Performing a DYN Calibration.

4.1 Calibration Setup

The WE430 Hydrazine analyzer provides simple and fast calibration cycles using a dynamic two point calibration procedure, which requires the use of the dynamic calibrator.

To perform a dynamic two point calibration, the WE430 analyzer is rst connected to a reductantfree sample stream. An appropriate diluted standard is prepared and then a syringe is lled

with the diluted standard and mounted on the calibrator. The calibrator is then mounted near the analyzer and the syringe tubing is connected to the standard injection port. By adjusting the

calibrator pump settings, two di󰀨erent ow rates produce two known standards that are diluted

into the sample background.

Prior to performing a calibration, refer to Section 3.1, Use of the Setup Mode for instructions on

how to properly congure the WE430 analyzer and set the analyzer to the hydrazine application

mode.

n DYN Calibration Recommendations

When the WE430 Hydrazine analyzer is rst commissioned, it is advisable to ush out uidics

system overnight prior to the initial calibration and use. The electronics need not be turned on at this time. Refer to Chapter 4, Rinsing the Flow Cell.

• Install the sensing electrode, reference electrode and ATC probe in their respective ow cell

holders. Refer to Section 2.6, Installation of a New Iodide Electrode, Section 2.7, Installation of ATC Probe and Section 2.8, Installation of a New Reference Electrode.

• To ensure the analyzer achieves stability and to minimize interference during calibration, the operator should minimize activity on the system during calibration.

• Maximum system accuracy is ensured through a fast, easy and accurate calibration performed in the expected sample range. This calibration procedure uses equipment supplied in the calibration kit including the dynamic calibrator.

• Wait at least one hour to calibrate the analyzer after changing the reagent.

• Use an oxygen scavenger-free sample during calibration.

• Fill and empty the syringe with standard at least three times before connecting the syringe to the dynamic calibrator.

• Always use a new syringe for each calibration.

4.3 Dynamic Calibrator and Syringe Setup

1. Connect the calibration tubing to the syringe using the luer adapter and the 1/4’’ female connector. Only hand tighten the components, do not overtighten them.

2. Loosen the blue knob on the dynamic calibrator by turning it approximately 1/4 of a turn clockwise and pressing up on the bottom, inside part of the blue knob. Lift the blue syringe

holder and turn it away from the syringe cradle. Set the lled syringe in the center syringe

cradle. Rotate the syringe holder back in place across the syringe. Gently tighten the blue knob by turning it 1/4 of a turn counterclockwise.

3. Lift the black drive carriage straight up. Move the carriage back and re-engage it with the gears, leaving room for the syringe. Check the alignment of the drive carriage to ensure it is perfectly straight.

4. Replace the drive carriage on the gears. Advance the carriage to meet the syringe by momentarily turning the pump on high speed.

NOTE

Do no attempt to push the carriage manually. This may result in damage to the pump mechanism.

5. Set the blue endpoint limiter midway between the white indicator marks.

4.7 Dynamic Calibrator Check

1. The normal ow rate from the 20 cc syringe when the dynamic calibrator percent ow dial is set to 500 (equals 50% ow) and when the range switch is set at x/1 is 20 mL/minute. Therefore, the ow rate at x/10 is 2 mL/minute and at x/100 is 0.2 mL/minute.

2. Place a 10 mL graduated cylinder so that the calibration tubing will reach the top of the cylinder.

3. Turn the pump range switch to x/100 and allow the ow to begin and to ll the tubing

completely, purging all air bubbles.

4. Simultaneously, insert the calibration tubing into the mouth of the graduated cylinder and start a stopwatch.

5. Allow the ow to continue into cylinder for exactly ten minutes. Remove the tubing from the cylinder and the pump o󰀨.

The total volume of the graduated cylinder should be 2.0 ± 0.1 mL.

If the total volume is not 2.0 ± 0.1 mL, the ow rate dial may be adjusted using the following

formula:

adjusted ow rate setting = present setting •

For example, if the actual total ow was 1.8 mL, the new ow rate

setting will equal = (500) • (2.0/1.8) = 555

6. Perform the same ow rate check with the range switch on x/10 using a 50 mL graduated cylinder. Set the percent ow dial to read 500 (50.0%).

7. Allow the ow to continue into cylinder for exactly ve minutes. Remove the tubing from the cylinder and turn the pump o󰀨.

The total volume of the graduated cylinder should be 10.0 ± 1.0 mL.

Fine adjustment of the ow rate dial may be made if the total ow is di󰀨erent from the

specied amount.

For example, if the actual total volume was 11.0 mL, the new ow rate

setting will equal = (500) (10.0/11.0) = 455

5.1 Maintenance Schedule

The WE430 Hydrazine analyzer is designed for simple maintenance. Follow the instructions in this section to ensure proper operation of your analyzer.

n Recommendations

To ensure proper maintenance and good analyzer performance, a service logbook should be kept.

• Record maintenance date and the type of service work completed.

• Mark the date and the uid levels of the reagent and the date when it was replaced.

• Tag each electrode cable with the installation date of the electrode.

5.2 Weekly Maintenance

1. Check that the sample ow rate is 35 to 45 mL/minute. To alter the ow rate, pull out the

locking knob of the pressure regulator, then rotate the black knob to increase (clockwise) or

decrease (counterclockwise) sample ow. Push in the locking knob of the pressure regulator to lock the ow rate.

2. Inspect the analyzer for leakage. Di󰀨usion tubing leakage is indicated by a rise in the level of

reagent.

3. Check that there are no error indications and that the current concentration level is reasonable.

4. Check that the reference lling solution is adequate.

5. If required, wipe the analyzer with a damp cloth to remove dirt and dust particles.

5-1

5.3 Bi-Weekly Maintenance

Refer to Section 2.8, Installation of a New Reference Electrode.

n Reference Electrode Filling Solution Replacement

WARNING

Turn o󰀨 the air pump prior to removing the reference electrode lling solution bottle. If the air pump is left on, it will spatter lling solution as the bottle is removed.

The reference electrode lling solution needs to be replaced approximately every two weeks. If

the reservoir is less than one quarter full, replace the solution. This should be checked every two weeks to ensure that the electrode does not run dry.

1. Remove the spent electrolyte bottle from the clip. Unscrew the cap and discard the bottle.

2. Remove the cap and seal from the new reference electrode lling solution. Check that the

rubber gasket is properly aligned and then connect the cap and tubing assembly to bottle. The 1/8’’ tubing should extend into the bottle.

3. Invert the electrolyte bottle and snap it into the clip.

4. Use the special pushpin attached to the pressurized reference assembly on the analyzer to pierce a hole in the bottom of the bottle and re-pressure the reservoir by the air pump.

5. Dry the frit at the base of the reference electrode. Check the frit to see if a bead of ll solution forms, which indicates good electrolyte ow.

IM 12Y18A03-01EN 1st Edition : Oct. 04, 2019-00

<5. Analyzer Maintenance>

5.4 Monthly Maintenance

Calibration frequency is operator dependent for the most accurate and precise measurements.

5.4.1 Calibration

• Replacement of the reagent requires calibration. Refer to Section 4.4, Performing a DYN Calibration.

• Calibration intervals can be programmed using the setup mode. This will prompt the

operator to recalibrate after a specic amount of time has passed. Refer to Section 3.1, Use

of the Setup Mode.

5.4.2 Replacement of Sample Inlet Filter

1. If the sample ow can be adjusted with the pressure regulator to 50 mL/minute or more, skip

this procedure.

2. Turn o󰀨 sample ow by turning the inlet valve to the right.

3. Remove the lter hex cap using a 1 inch open-ended wrench.

4. Separate the lter cap with bypass/needle valve assembly from the lter body, retaining the

ring.

5. Remove the lter element and soft gasket (if necessary).

6. Replace the gasket and press a new sintered element into the lter body.

7. Replace the hex cap and bypass/needle valve assembly and reposition the bypass drain line into the drain assembly.

8. Retighten the hex cap to approximately 75 pound-inch in torque.

9. Turn on the sample ow by turning the inlet valve left.

10. Check for leaks.

5-2

5.4.3 Polish Iodide Electrode

Refer to Section 2.6, Installation of a New Iodide Electrode.

Polish the iodide electrode according to the instructions that are included with the polishing strips.

Rinse the electrode thoroughly with distilled water, insert the iodide electrode into its holder in the

ow cell and then plug the electrode cable marked “Sensing” into the top of the electrode.

5.4.4 Air Pump Check

The reference electrode ll solution level should drop at least 1/8’’ per month, which indicates good ow through the electrode frit. If the ow rate is low, the air pump should be tested for

proper operation.

To test the air pump, remove the pushpin and tubing from the reference reservoir. Place the tip of the pushpin in a beaker of water. Vigorous bubbling should be observed. Normally, the air pump delivers at least 500 cc/minute of air. Replace the air pump if weak bubbling or no bubbling is

observed. To ensure a tight seal on the reservoir, replace it with a fresh bottle of ll solution (Cat.

No. 181073).

5.4.5 Replacement of Reagent and Di󰀨usion Tubing Assembly

6.2 Slope Problems

6.2.1 Low Slope

Slope less than -40 mV/decade

• Check the electrode function, clean the electrode, recalibrate the analyzer, and if the analyzer continues to read low, replace the electrode.

• An oxygen scavenger-free sample must be used for calibration.

• Check electronics to read mV input correctly. Use electronic test kit procedure for checking electronics function.

Ion-selective electrodes (ISE) can be shown as DC-voltage sources with 50 to 1000 Megohm; a very high output impedance. ISEs respond to ion concentration changes with a voltage change of approximately -59 mV/decade for monovalent anions such as iodide. Knowing electrode and

analyzers parameters like o󰀨set potential, slope, etc allows testing of various instruments by

applying a known mV voltage.

Input Signal Expected Reading: ± (0.5 mV + 0.1%)

0 mV - 0.5 mV to + 0.5 mV

- 1000 mV -1001.5 mV to – 998.5 mV + 1000 mV + 998.5 mV to + 1001.5 mV

• Standards contaminated or incorrectly made – verify calibration with fresh standards.

• Standard 1 and standard 2 values not set correctly – check the percent ow rate setting and

range setting on the dynamic calibrator and in the setup mode of the analyzer. If using a custom standard, verify the values for the dynamic calibrator.

• Standard 1 and standard 2 added in wrong sequence – check the sequence of the standards and repeat the calibration.

• pH adjustment is not correct – check the level and ow of the reagent. Replace the reagent

if it is contaminated or the level is less than 50 mL. Refer to Section 2.4, Installation of

Reagent and Di󰀨usion Tubing.

6-5

6.2.2 High Slope

Slope greater than -75 mV/decade

• Improper calibration technique – refer to Section 4.4, Performing a DYN Calibration.

• Calibration standards contaminated – repeat the calibration using fresh standards.

• Electronics failure – reset the analyzer. Refer to Section 6.4, Resetting the Analyzer.

• Improper dynamic calibrator settings – refer to Section 4.4, Performing a DYN Calibration.

• An oxygen scavenger-free sample must be used for calibration.

• Cables interchanged – verify wiring of cable connections to terminal strip. Refer to Section

2.3, Wiring the Analyzer.

• Check the connection of the cable markers for the corresponding electrode. Cable markers are the white tape at the cap connector on the cable.

• “Ref” for the reference electrode.

• “Sensing” for the iodide electrode.

• Sensing electrode coated – clean or replace the sensing electrode.
