Section 3 Analyzer Overview
3.1 Operation
The 9210 can analyze up to six different samples. The sample to be analyzed 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
measuring cell (4) with the use of a solenoid valve (5).
The reagents R1M and R1A are first added using two of the reagent pumps (9). The silica
contained in the sample then reacts with the molybdate and forms the silicomolybdic complex.
The reaction will take up to 5 minutes.
Oxalic acid is then added using a reagent pump (9) to avoid phosphate interference and to
intensify the color.
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.

Analyzer Overview
3.2 Calibration
In order to ensure accurate measurements, the analyzer should be calibrated periodically. The
zero is achieved chemically and internally in the analyzer. The system slope is controlled by
comparison to a standard solution of known concentration. Further information regarding
calibrations can be found in the section entitled Calibration on page 51.
3.3 Analyzer outputs
The instrument can measure silica concentration from three different sources:
•the process sample during a normal measuring cycle
•the calibration solution during an automatic calibration
•an external sample during the grab sample operation
Whatever the sample source, the measurement cycle structure is identical and all analyzer
outputs (e.g. 4/20 mA outputs, screen display, RS485 data, alarm status, etc.) are refreshed
during the last minute of the measurement.
3.4 Maintenance
To ensure a high degree of accuracy is maintained by the analyzer, it is recommended to
perform a specific maintenance procedure once a year. All replacement parts and fittings are
available by purchasing the maintenance kit 09120=A=8000 which contains enough parts and
fittings for two years.
Full details on this procedure and the contents of the maintenance kit can be found in Yearly
maintenance on page 60.

Section 4 Installation
WARNING
The analyzer should only be assembled by qualified staff. Mains power should only be
connected once installation has been completed and checked.
4.1 Analyzer inspection and unpacking
The analyzer has been factory tested and checked prior to shipping. We nevertheless
recommend that you perform a visual inspection in order to ensure that it has not been
damaged. Any marked packaging is a potential sign of damage that may not be immediately
visible. Keep all packaging in the event of claims.
Open the box. Take the packing list from the box and check the presence of all the items
selected. If any parts or accessories are missing, refer to your distributor or to Hach Lange.
4.2 Analyzer preparation
Before installing the analyzer, think about the following:
•Place the analyzer close to the sample point. This will allow the response time to be reduced.
•The sample should be homogenous and representative.
•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.
•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 analyzer should not exceed 45°C. If the temperature is
below 5°C, the analyzer should be installed in a heated cabinet (not provided by Hach
Lange).

4.4 Mounting the analyzer
CAUTION
Wherever the analyzer is to be mounted, it is important to note that it must be placed in
an upright position with the transmitter at the top. It is recommended to use a spirit level
to ensure that the analyzer is correctly positioned and not leaning to one side or forward.
This is essential to guarantee the accuracy of the analyzer.
