8General Information2.2 General information about the probeThe probe was developed for use in municipal wastewater applications.The AN-ISE sc probe (please refer to Figure 2) with ion-selective electrodes (ISE probe) is a continuously operating online process probe for directly measuring ammonium and nitrate in reservoirs. It operates without reagents and requires no further processing of the sample. The ammonium/nitrate ions are measured using an ion-selective electrode.The only wearing part is the sensor cartridge (please refer to Figure 3, Page 9) (order number LZY694). The sensor cartridge consists of the ion-selective electrodes for ammonium and potassium (compensation electrode for ammonium) or nitrate and chloride (compensation electrode for nitrate), a pHD reference system and a temperature sensor for temperature compensation.An additional cleaning unit designed for automatically cleaning the sensor cartridge membranes can be ordered separately. Refer to the instruction sheet supplied with the cleaning unit.The manufacturer recommends using the High Output Air Blast system for the compressed air supply (refer to 7.2 Accessories, page 39); this is a compressor in weather-proof plastic housing.

9General Information2.3 Theory of operationThe AN-ISE sc probe uses the ion-selective electrode to measure ammonium ions (NH4+) and nitrate ions (NO3–) in a wastewater sample. Common interfering factors due to potassium, chloride and temperature are compensated for by means of the relevant built-in electrodes. The reference system is designed using pH-differential technology and is therefore particularly stable in terms of drift and contamination.Ion-selective electrodes have a special membrane to which only a specific type of ion can adhere. As a result an ion-specific potential forms on the membrane surface. To measure a potential difference, a reference system is required that will not be affected by the sample to be measured.The CARTRICALTM technology reduces cross sensitivity by calibrating not only the individual electrodes against each other, but also the measuring electrodes with the compensation electrodes and the reference; this is carried out at the factory.Figure 3 Sensor cartridge1Ammonium electrode 5Reference system2Nitrate electrode 6Temperature sensor3Potassium electrode 7Marker hole for assembling the probe4Chloride electrode

25Operation4.6 Calibration/Matrix correctionThe four electrodes with the reference system of the compact sensor cartridge were calibrated with one another at the factory using special standard solutions (CARTICALTM). However, the membranes on the ion-selective electrodes are not 100% selective due to other substances that may affect the measurement. Perform a matrix correction (refer to 4.6.4 on page 27) to compensate for other ions present on the ISE electrodes.Potassium has the largest interference effect on the ammonium membrane, while chloride has the largest effect on the nitrate membrane. The AN-ISE sc sensor compensates for this with the aid of a built-in potassium/chloride electrode.Cross sensitivities between ammonium, potassium/nitrate and chloride are automatically eliminated. Solids do not interfere with the measurement. Due to matrix effects, correction and validation cannot be performed with standard solutions. A matrix correction can be carried out quickly and easily at any time.SENSOR SETUPTEMP Display the signals and measurement results for temperatureHUMIDITY Display the signals and measurement results for humidityRFID Display the signals and measurement results for RFIDCAL DAYS Display the age of the last matrix correction for ammonium and nitrateAMMONIUM Display the age of the last matrix correction for ammoniumNITRATE Display the age of the last matrix correction for nitrateSERVICETEST CARTRIDGE Perform a sensor check with the test cartridgeTEST CARTRIDGE FERTIG?

This is the minimum time required to adapt the ISE membranes to the wastewater matrix.
26Operation4.6.1 Sensor code calibrationThe sensor code is a calibration code and is delivered with the sensor cartridge certificate. It contains the factory calibration described in section 4.6 on page 25 for the sensor cartridge. Instruments with automatic sensor code recognition (LXG440.99.0000x) read this automatically and assume the Cartrical calibration.Instruments without automatic sensor code recognition (LXG440.99.0001x) require the sensor code to be entered during the initial setup and whenever a new sensor cartridge is activated. If the sensor code certificate has been lost, please carry out factory calibration (under the sensor code menu) as a temporary solution.After activating the code, the sensor is fully calibrated but not yet adapted to the specific matrix of the relevant application on a wastewater treatment plant. At least 12 hours must elapse before a matrix correction is performed to allow the cartridge to adapt to the specific matrix.To change the sensor code: 1. Select SENSOR MENU>AN-ISE SC>CALIBRATE>FURTHER CORR.>SENSOR CODE>ENTER2. Enter the sensor code.3. Press ENTER to confirm and activate the sensor code. The day meter for the cartridge is set to zero.All old calibration data are now overwritten with the new calibration data from the sensor code. The sensor code data are checked by the system. If an error is indicated, check the sensor code and if necessary repeat the entry of the sensor code.4.6.2 Matrix correction via LINK2SCThe LINK2SC procedure offers a secure method of data exchange between processprobes and LINK2SC-compatible photometers using an SD memory card or via a localarea network (LAN). There are two different options are available:a. The pure laboratory control measurementb. A matrix correction that involves the measurement data generated in the laboratory being used to correct the probeDuring a pure control measurement, the measurement data is transferred from the proveto the photometer where it is then archived together with the photometric reference datathat has been recorded.During a matrix correction, the reference data generated in the laboratory is transferred tothe probe where is used for the correction.The matrix correction process requires operating steps to be completed on the sccontroller and on a LINK2SC-compatible photometer.Please refer to the LINK2SC user manual for a detailed description of the LINK2SCprocedure.When using the LINK2SC software, sections 4.6.3 and 4.6.4 are not relevant.4.6.3 Matrix correction overviewThe AN-ISE sc sensor offers different options (refer to Table 1) for correcting the sensor value with laboratory values (as a reference value).
Table 1 AN-ISE sc sensor correction options Correction Option ApplicationMATRIX 1VALUE CORR. 1VALUE CORR. 2MATRIX 2HIST. CORR. 27OperationThe laboratory value of the water sample is entered as nitrate-nitrogen (NO3–N) or as ammonium-nitrogen (NH4–N). This laboratory value replaces the prior value measured by the sensor.4.6.4 Performing the matrix correctionNote: Take laboratory value measurements or reference values promptly or, alternatively, take these from the stabilized sample. This will prevent changes in sample concentration, as time is a factor in comparative tests.Refer to 7.3 Validation accessories, page 39 for recommended laboratory measurement tests.4.6.4.1 MATRIX 1 correction (1 point matrix correction)Proceed as follows to perform MATRIX 1:1. Select SENSOR MENU>AN-ISE SC>CALIBRATE>MATRIX CORR.2. Select MATRIX 1 from the selection window and press ENTER.3. Select the parameters you wish to correct and confirm by pressing ENTER. Selection options: NH4 + NO3; NH4; NO3; NH4 + K; NO3 + Cl; NH4 + K NO3 + Cl. A MATRIX 1 is the most commonly used correction option and performs a 1 point matrix correction for ammonium and/or nitrate (4.6.4.1 on page 27). It is advisable to perform a MATRIX1 as the first correction. The Matrix1 correction can be performed both with and without correction of the compensation electrodes (potassium or chloride); in most cases, it is sufficient to perform it without correction of the compensation electrodes. A correction featuring potassium and chloride is only necessary if a high level of accuracy is required. With a MATRIX1, a sample must be taken when the correction is triggered and analyzed in the laboratory. The MATRIX1 is activated when the laboratory value is entered.Value correction 1 (correction at one concentration point) corresponds to a MATRIX1 correction with an alternative entry format. Comparison values between AN-ISE sc and the laboratory can be collected over a period of around a week with this correction. The correction can be performed at a later stage.Value correction 2 (correction at 2 different concentration points) should be performed if dynamic concentration fluctuations are present over at least half a decade1 and a MATRIX1 or VALUE CORR. 1 does not achieve a sufficiently accurate result. Comparison values between AN-ISE sc and the laboratory can be collected over a period of around a week with this correction. The correction can be performed at a later stage.The MATRIX 2 correction corresponds to a VALUE CORR.2, but uses an alternative entry format and is recommended if there is a dynamic process with a large nitrate/ammonium fluctuation over at least half a decade1. With a MATRIX2, a sample must be taken for both points when the correction is triggered and analyzed in the laboratory. The MATRIX2 is activated when the laboratory value is entered. Return to one of the last matrix and value corrections performed if a correction has not produced a successful result.1 Examples of half a decade: The concentration of nitrogen nitrate shifts between 1 and 5 mg NO3–N or between 5 and 25 mg/L NO3–N.

28OperationThe sensor saves the current values of the selected parameters at this point.4. Take a water sample immediately from the closest point possible to the sensor. Filter the sample as quickly as possible and carry out a prompt laboratory analysis of the selected parameters, as the measurement value can change quickly.When the laboratory value has been determined, proceed as follows:5. Select SENSOR MENU>AN-ISE SC>CALIBRATE>ENTER LABVALUE6. The laboratory values for the parameters can only be entered if the MATRIX1 correction has been selected beforehand. Once the laboratory values have been entered, select ENTRY COMPLETE to confirm.When the entered laboratory value is confirmed, the matrix correction is activated.7. Once the correction is activated, the result CORR-RESULT is shown.Note: This process must always be carried out in full to make sure the matrix correction is completed successfully. If a correction does not produce a successful result, calculations are made with the previous correction.4.6.4.2 Value correction 1The one-point value correction VALUE CORR. 1 offers the option of retrospectively performing a matrix correction at one point (MATRIX1).1. Take several samples with different concentrations on various days, preferably within one week. Analyze the samples in the laboratory. During the time the samples are being taken, the sample temperature should be around a maximum of 5 °C, as temperature changes are not taken into account in the value correction.2. Make a note of the two values measured in the samples and displayed for the parameters to be corrected (ammonium and potassium values, or nitrate and chloride values)3. Also note the laboratory values measured for ammonium or nitrate. These three values form the correction point.4.

29Operation4.6.4.3 Value correction 2The two-point value correction VALUE CORR. 2 makes it possible to perform a subsequent 2-point correction (MATRIX2) to achieve higher accuracy for a larger concentration range. Note: Value correction 2 and MATRIX 2 are comparable from a calculation perspective.1. Take several samples on various days with different concentrations, preferably within a week, and perform an analysis of the samples in the laboratory. During the time the samples are being taken, the sample temperature should be around a maximum of 5 °C, as temperature changes are not taken into account in the value correction.Note: The VALUE CORR. 2 concentrations should be within a range of over half a decade. The following formula can assist in the calculation of the half decade: 2. Make a note of the two values measured with the sensor in the samples and displayed for the parameters to be corrected (ammonium and potassium values, or nitrate and chloride values).3. Also note the laboratory value measured for ammonium or nitrate.All three values form one of the two correction points.4. Look for two correction points where the laboratory values are at least half a decade apart and display typical operating conditions for the installation. 5. Go to the sensor menu and select CALIBRATE>MATRIX CORR>VALUE CORR. 2 then confirm with ENTER.6. Select the parameter (NH4–N or NO3–N) that requires correction.Note: Only one parameter can be corrected at a time. If both need to be corrected, the procedure must be performed again.7. Enter the three values for the first correction point and confirm with ENTRY COMPLETE.8. To activate the correction, enter the three values for the second correction point and confirm with ENTRY COMPLETE.Correction result CORR-RESULT is shown.Note: If a correction does not produce a successful result, calculations are made with the previous correction.

Clean the sensor cartridge with the soft brush supplied. 2. Clean the probe body (not the sensor cartridge) with a sponge or brush.3. Rinse the sensor with clean, lukewarm water.5.2.1 Polish the chloride electrodePolish the chloride electrode if it looks heavily coated/contaminated. After polishing, a new nitrate + chloride MATRIX1 correction should be performed after 12 hours.Only qualified personnel should conduct the tasks described in this section of the operating manual.5.1 Maintenance scheduleClean the probe2 xReplace the sensor cartridge3, 4xCheck probe for damage xCompare the measured value with a reference laboratory analysis and correct the values as required via a matrix correction3 x1 Recommended: Weekly during the first month of operation2 The frequency of cleaning depends on the application. Some applications may require cleaning to take place more or less frequently. 3 In typical operating conditions, a different interval may be required depending on the specific application and local conditions. 4 Sensor cartridges are wear parts and are not covered by the instrument warranty. Do not touch the membranes with fingers. Do not clean the sensor cartridge with sharp objects that may cause scratches and do not use any chemical cleaning agent.Only use the LZY671 polishing paper supplied.

Pull the sensor cartridge out of the probe adapter and dispose of the old sensor cartridge as per the applicable regulations.5. Make sure that a new black gasket is installed every time the sensor cartridge is replaced. Before the gasket is installed, clean the surface that faces the cartridge and the groove for the gasket.6. Insert the new sensor cartridge into the probe adapter. Observe the marker hole on the sensor cartridge flange and the probe adapter.7. Secure the sensor cartridge with the 4 socket head screws. 8. The sensor code (calibration data) is automatically read for instruments with automatic recognition (LXG440.99.0000x). For instruments with non-automatic recognition (LXG440.99.0001x), enter the new sensor code manually (refer to certificate). The sensor cartridge must point downward such that no water can run into the probe adapter. Pay attention to the contacts between the probe and the sensor cartridge. The contacts have to remain dry.

NOTICENOTICE34Maintenance5.4 StorageTake the probe out of the sample flow and clean thoroughly.Short term storageKeep the membranes and the reference system wet (DO NOT USE DISTILLED OR DEMINERALIZED WATER). Drinking water is advised.This will help avoid long response times when the probe is placed back in the sample flow. Otherwise, the correct operation of the probe is no longer guaranteed.Long term storageCheck the membranes and ensure they are still moist every 2–4 weeks, depending on environmental conditions.Note: A storage container is supplied to keep the sensor cartridge moist. Keep sensor cartridge capped within the storage container during short and long term storage. Refer to Section 1 Specifications, Page 5 for storage temperatures.Probe and sensor cartridgeDetach the cartridge and use the supplied storage container in the event of long-term storage. Moisten the little sponge in the storage container with drinking water (DO NOT USE DISTILLED OR DEMINERALIZED WATER) and make sure that the ISE membranes of the sensor cartridge remain wet. Attach the reference system cap.Pay attention to the contacts between the probe and the sensor cartridge. The contacts must be dry.
