Calcium reagents, oxalate method, 50 tests

The HI-937521-01 are reagents for the colorimetric determination of calcium using a compatible benchtop or portable photometer. These high quality reagents are clearly marked with the lot number and expiry date on each bottle for traceability. These reagents follow an adaptation of the oxalate method. The reaction between calcium and reagents causes a colour tint in the sample. By adding the HI-937521-01 reagents to the sample, a reaction will take place and a compatible photometer can be used to determine the concentration from the colour that is produced. The results will be displayed in mg/L (ppm) as calcium. These reagents are designed to be used with samples that have an expected range of 0 to 400 mg/L calcium.
