General description

Method: photometric 0.25 - 500.0 µg/l SiO₂ 0.12 - 233.7 µg/l Si Spectroquant®

The method is analogous to APHA 4500-SiO2 D+E, ASTM D859-10, and DIN 38405-21.

This Spectroquant® Silicate Reagent Test allows the accurate quantification of silicate (silicic acid) in aqueous samples.

Method applied: In sulfuric solution silicate ions react with molybdate ions to form a yellow heteropoly acid which is reduced to silicomolybdenum blue. This dye is determined photometrically.

The Spectroquant® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.

All our Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.

Ultrasensitive Determination of Silicate in Process and Boiler Water Using Rapid Photometric Tests

Efficiency of industrial plants and equipment constitutes one of the basic preconditions for sustainable economic operations. One avoidable problem is posed by the undesirable build-up of deposits, i.e., scale – in pipes, boilers, and turbines, whose principal cause is silicate. A rapid and sensitive test can ensure control over this threat.
