Technical Information

Stamolys CA71SI

Silicate Analyzer

Compact photometric analysis system for the silicate measurement in

ultrapure water and boiler feedwater

Application

• Ultrapure water

• Boiler feedwater

• Steam and condensate analysis

• Reversed osmosis

• Demineralizers

Industries:

• Pharmaceutical industry

• Power stations

Your benefits

Stamolys CA71SI measures the silicate content quasi-

continuously to assure a constant optimum water quality. This is

of special advantage in the performance monitoring of ion

exchange and reversed osmosis systems. The analyzer replaces

frequent manual sampling and exactly determines the silicate

break through of the system.

• Stainless steel or glass-fibre reinforced carbon housing

available

• Two channel version available

• Measured value storage using integrated data logger

• Automatic calibration and self-cleaning

• Free selectable measuring, cleaning and calibration intervals

Function and system design

Measuring principle upper

measuring range (SI-B)

After sample conditioning, the analyzer sample pump conveys a part of the filtrate to a mixing vessel. The

reagent pump adds reagent at a specific ratio. As a result of the reaction, the sample turns a characteristic

colour. The photometer determines the sample’s absorption of an emitted light at a specific wavelength (s. Fig.,

Pos. 2). The wavelength is parameter specific. The absorbance is proportional to the concentration of the

specified parameter in the sample (Pos. 3). Additionally, the absorption of a reference light is determined to

receive a genuine measuring result. The reference signal is subtracted from the measuring signal to prevent any

effects due to turbidity, contamination and ageing of the LEDs.

The temperature in the photometer is controlled thermostatically so that the reaction is reproducible and takes

place within a short period of time.

Measuring principle lower

measuring range (SI-A)

The LED sends light at a defined wavelength through the sample. The intensity of the received light is

measured by the detector and converted to an electrical signal. In the analyzer, the respective concentration is

calculated from the proportion of light absorbed by the sample.

Silicate With 18% silicon is the second most frequent element of the earth crust. It occurs chemically bonded as silicate

or silicon dioxide in a variety of minerals. From these minerals silicate or silicic acid is washed out in low

quantities to waters.

There are no standard limits for drinking water since silicate is not known to be harmful to health.

But in boiler feed water and boiler water, there may be only low silicate concentrations because under thermal

charge or under high pressure insoluble silicon dioxide is formed. It solidifies in boilers, heat exchangers and

turbine blades and thus reduces the heat exchanger’s efficiency or causes overheating.

The standard limit for boiler feed water is 0.02 ppm silicic acid (SiO2). For injection and boiler water the

standard limits are pressure dependent. For example, at an operational pressure of 68 bar (986 psi), the

concentration of silicic acid in boiler water must not exceed 10 ppb.

Photometric detection Heteropoly blue method for silicate determination

Under acidic conditions silicate and phosphate react with molybdate to form yellow silicomolybdic and

phosphomolybdic acid complexes. Addition of citric acid destroys the phosphate complexes. Last step is the

addition of an amino acid. It reduces the yellow silicomolybdic complex to intensively blue silicomolybdic blue.

The absorption is determined at a wave length of 810 nm. The absorption intensity is proportional to the silicate

concentration in the sample.

Interferences

Sample conditioning Analyzer and membrane filtration (Stamoclean CAT411)

A sample flow of 0.8 to 1.8 m3/h (3.5 to 8 gal/min) is continuously conducted through the micro filter via a

pressure pipe. A part of the sample passes the filter membrane and is then conveyed to the measuring device

as filtrate.

Sampling is based on the cross flow filtration principle. The PTFE filter membrane separates particles with sizes

> 0.45 μm from the filtrate. These particles are collected in front of the membrane and are washed away with

the sample flow.

The medium is conducted in a meander-like channel through the filter element. This results in a constantly

high flow rate. The high flow rate generates the self cleaning effect. Therefore, mechanical drives for the

generation of a flow at the filter surface are not necessary.

Analyzer without Endress+Hauser sample conditioning

Before analysis, the sample has to be conditioned, homogeneous and to be transported to an external or to the

delivered collecting vessel.

Open version (without housing)

With the open version, you need an additional platform for the reagents. Mount this platform max. 35 cm

(13.8 inch) below the pumps. The reagent bottels have the following dimensions: 90 x 90 x 215 mm (3.54 x

5.54 x 8.46 inch). The number of bottles varies from 2 to 5 depending on the analyzer version.

For these versions, the outlet pipe must be installed right of the analyzer.

The outlet pipe must be mounted to a wall so that the sample outlet hoses from the photometer have a gradient

of 5 to 10 %. If neccessary, extend the hoses.
