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 (NH
and nitrate ions (NO
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.

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 (CARTICAL
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.

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.

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:

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

The laboratory value of the water sample is entered as nitrate-nitrogen (NO3–N) or as
ammonium-nitrogen (NH

–N). This laboratory value replaces the prior value measured by

4

the sensor.

Tabl e 1 AN-ISE sc sensor correction options

Correction Option Application

A MATRIX 1 is the most commonly used correction option and performs a 1 point matrix

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
