Sulfate LR / HR, barium chloride method, Reagent kit for 100 tests (SO₄²-)

The HI38001-10 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate sulfate measurements with the chemical test kit. These reagents follow a barium chloride titration method to determine sulfate concentration. 

For determination of sulfate, the reacted sample is titrated with barium chloride solution. A color change from violet to blue indicates the endpoint of the titration. The number of milliliters of titrant used to reach the visual endpoint will determine the sulfate concentration in mg/L. These reagents are designed to be used with low and high range samples with an expected sulfate concentration of 100 to 1000 mg/L and 1000 to 10000 mg/L SO₄^2-.
