Sulphate, barium chloride method, Reagent kit

The HI-38000-10 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate sulphate measurements with the chemical test kit. These reagents follow the barium chloride turbidimetric method to determine sulphate concentration.

For determination of sulphate, the barium chloride reagent is added to an acidified sample. The reaction between sulphate ions and the reagent creates a barium sulphate suspension. The supplied glass test tube is then filled slowly with the reacted sample. When the black indicating spot on the bottom of the test tube is no longer visible, the level of liquid in the test tube indicates the concentration of sulphate in mg/L (ppm). These reagents are designed to be used with samples that have an expected sulphate range of 20 to 30 mg/L and 30 to 100 mg/L.
