General Information
2.2 General information about the probe
The 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.

2.3 Theory of operation
The 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.

4.6 Calibration/Matrix correction
The 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.
NOTICE
A matrix correction may only be performed if the sensor has been immersed in the corresponding
wastewater matrix for over 12 hours. This is the minimum time required to adapt the ISE
membranes to the wastewater matrix.
25
Operation
4.6.1 Sensor code calibration
The 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>ENTER
2. 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 LINK2SC
The LINK2SC procedure offers a secure method of data exchange between process
probes and LINK2SC-compatible photometers using an SD memory card or via a local
area network (LAN). There are two different options are available:
a. The pure laboratory control measurement
b. A matrix correction that involves the measurement data generated in the
laboratory being used to correct the probe
During a pure control measurement, the measurement data is transferred from the prove
to the photometer where it is then archived together with the photometric reference data
that has been recorded.
During a matrix correction, the reference data generated in the laboratory is transferred to
the probe where is used for the correction.
The matrix correction process requires operating steps to be completed on the sc
controller and on a LINK2SC-compatible photometer.
Please refer to the LINK2SC user manual for a detailed description of the LINK2SC
procedure.
When using the LINK2SC software, sections 4.6.3 and 4.6.4 are not relevant.
4.6.3 Matrix correction overview
The AN-ISE sc sensor offers different options 
(refer to Table 1) for correcting the sensor value with laboratory values (as a reference
value).
26
Operation
The 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.
Table 1 AN-ISE sc sensor correction options
Correction Option
Application
MATRIX 1
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 CORR. 1
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 CORR. 2
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.
MATRIX 2
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.
HIST. CORR.
Return to one of the last matrix and value corrections performed if a correction has not produced
a successful result.
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. (conc2 = (conc1 x 10)/2)
1 Examples
4.6.4 Performing the matrix correction
Note: 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.

INFORMATION
The 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. From the values taken, select a correction point that lies in the middle of the expected
concentration range.
