SILICATE (SILICIC ACID) TEST

General description

Method: photometric 1.1 - 1070 mg/l SiO₂ 0.5 - 500 mg/l Si Spectroquant^®

The method is analogous to APHA 4500-SiO2 C.


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 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.
