General description
Method: colorimetric with color-disk comparator 0.3 - 0.6 - 1.0 - 1.5 - 2 - 3 - 5 - 7 - 10 mg/l Si MQuant®
The MQuant® Silicate (Silicic Acid) test (formally MColortest®) can be used for the determination of silicate e.g. in:
Method
In sulfuric solution silicate ions react with molybdate ions to form a yellow heteropoly acid. This is reduced to silicomolybdenum blue. The silicate concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation.
The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
Using the refill pack 1.18323 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
- Groundwater, surface water, and seawater
- Drinking water and mineral water
- Industrial and process water
- Boiler water and boiler feed water
- Wastewater and percolating water
