SILKOSTAT 9210
Operation
The 9210 can analyse up to six different samples. The sample to be
analysed circulates in a fast loop permitting rapid renewal of the sample.
Adjustment of the flow is carried out with the help of a needle valve (2). At
the beginning of the analysis, the sample is introduced into the
measurement cell (4) with the help of a solenoid valve (5).
The 1st reagent is added with the pump (9). The silica contained in the
sample now reacts with the molydate and forms the silicomolybdic
complex. The reagent time is relatively long.
Oxalic acid is then added to avoid the interference of phosphates and to
intensify the colour.
The silicomolybdic complex is reduced to a blue molybdenum complex by
means of ferrous ions. A photometric measurement is carried out at the
end of the reaction.

Calibration
In order to ensure correct functioning, the analyser should be calibrated
periodically. The zero is realised chemically and internally in the analyser.
The system slope is controlled in comparison to a standard solution of
known concentration.

3. Installation
Unpacking
The instrument should be unpacked with care. Be careful not to mislay
the accessories during unpacking.
Caution :
Assembly should not be carried out by non-qualified personnel.
The power supply should not be connected until the installation
has been completed and checked.
Inspection
The instrument has been tested and checked at the factory before
shipping, however it is advisable to carry out a visual inspection to be
sure that it has not suffered any damage. Damaged packaging could
mean the presence of damage not immediately visible. Keep the
packaging in case of complaints. For any missing parts or accessories,
please contact your distributor.
Pre-installation
Before installing the analyser, think about the following precautions:
•Place the analyser close to a sample point. The sample should be
homogenous and representative. This will allow the response time to
be reduced. The temperature of the sample should be between 5 and
50°C. The pressure of the sample should be between 0.2 and 6 bar
and remain relatively stable. The solution should be free of particles.
The sample lines should be in PE/PTFE/FEP (∅4 x 6 mm).
•Avoid any location with a corrosive atmosphere or subject to liquid
spills.
•Chose a dry and dust-free location.
•The ambient temperature of the analyser should not exceed 45°C. If
the temperature is below 5°C, the analyser should be installed in a
heated cabinet.
