The HI38067-100 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate silica measurements with the chemical test kit. These reagents follow the heteropoly blue method to determine silica concentration.
For determination of silica, the acidified molybdate reagents react with silica present in the sample. The reaction between silica and the reagents causes a blue colored complex to form; the greater the concentration, the deeper the color. A Checker Disc is included for an accurate, side-by-side, visual analysis to determine silica concentration. These reagents are designed to be used with samples that have an expected silica range of 0 to 40 mg/L and 0 to 800 mg/L SiO2.
