QuantiChrom™ Sulfate Assay Kit

Why is a small amount of the standard added to the working reagent A.

This assay is based on the precipitation of insoluble barium sulfate which is measured turbidimetrically. Barium sulfate is minimally soluble, though, and to saturate the working reagent with soluble barium sulfate, you have to add a little of the sulfate standard to reagent A (which only contains barium). After that preparation step, all additional sulfate from your sample will precipitate when the working reagent is added allowing you to measure it.For more detailed product information and questions, please feel free to Contact Us.
