AMI Silitrace
Product Description
2. Product Description
2.1. Description of the System
Application
Range
The AMI Silitrace is a complete monitoring system for the automatic,
continuous measurement of the dissolved silica content in water
steam cycles or demineralizer plants.
Photometrical
Detection of
Silica
The determination of silica is done by the photometric analysis of
molybdate blue at 815 nm.
Silica and ortho-phosphates react at low pH with ammonium mo-
lybdate to the yellow colored molybdosilic acid respectively molyb-
dophosphoric acid. The molybdophosphoric acid is destroyed with
oxalic acid before the molybdosilic acid is reduced with iron-(II)-am-
monium-sulfate to the heteropolyblue complex.
Especially the reaction speed of the first reaction step to the molyb-
dosilic acid is relatively slow. It is the most time consuming part of
the whole reaction. As the reaction speed increases with increasing
temperature, it is time saving to heat up the sample. The AMI Sili-
trace therefore uses a thermostatic reaction chamber with a con-
stant temperature of 45 °C.
At 45 °C the complete reaction only needs 150 s (2.5 min). Be-
cause the reaction time plays an important role in the color devel-
opment, the pump speed is adjusted constantly. Due to the
automatic heating and reaction time regulation a very high preci-
sion is achieved.
Instrument
variants
The AMI Silitrace is available in two variants:
AMI Silitrace
AMI Silitrace Dual-Stream
Both instruments are identical except that the AMI Silitrace Dual-
Stream includes a channel selector valve.
Sample
Sequencer
If measurement of more than two sample streams is required, the
AMI Silitrace can be connected to a Sample Sequencer, which al-
lows to measure up to six sample streams.
Automatic
calibration and
verification
A calibration, verification or zero measurement can be performed
automatically according to a programmed time schedule or started
manually.

10 A-96.250.811 / 091017
AMI Silitrace
Product Description
Fluidic The sample enters at the sample inlet [N] and flows through the
flow meter [P], where the flow rate is measured, to the 6-way valve
[I]. A part of the sample overflows into the sample outlet [O].
The peristaltic pump [S] sucks the sample from the 6-way valve and
pumps it into the reaction chamber [D]. In the reaction chamber a
coil is wrapped around a heating device. It has 4 inlets to allow dos-
ing of the necessary reagents.
In the reaction chamber the sample is preheated to 45°C, eliminat-
ing temperature deviations of the sample. In a first step Ammoni-
ummolybdate [J] and sulfuric acid [K] are added, to form the
yellowish molybdosilic acid and molybdophosphoric acid.
Afterwards the oxalic acid [L] is added to mask the molybdophos-
phoric complex. At last the reducing agent ammonium ferrous (II)
sulfate [M] is added. The color of the sample turns to blue. As silica
is only present in trace amounts, the blue color can not be seen.
Afterwards the colored sample flows into the thermostatic cuvette
[E] until it is filled completely. Now the intensity of the color is mea-
sured at 815 nm. The color development is proportional to the silica
concentration in the sample.reaction chamber.
As the level of the sample in the cuvette increases, the sample
overflows into the siphon tube [G] and eventually the cuvette is
drained spontaneously through the siphon tube. The sample is led
via the aeration and drain tube [T] into the sample outlet [O].
Dosing, mixing and filling of the photometer are determined by the
rotating speed of the peristaltic pump [S]. This speed is adjusted
automatically and guarantees the correct timing of the measure-
ment.
The solenoid valve [R] is used for the zero measurement. It switch-
es off the supply of reagent 1, which is responsible for coloring the
sample. A zero can be started automatically or manually.
For a calibration or a verification the standard [B] is used. Both, cal-
ibration and verification can be started automatically or manually.
When a calibration or a verification is started, the 6-way valve is ro-
tated to position 5 and standard is pumped through the photometer.
NOTICE: The fluidic scheme shows the single-stream variant of
the AMI Silitrace. The dual-stream variant is fitted with a
different flow cell block and a channel selector valve (see AMI
Silitrace Dual-Stream, p. 34).
