The HI93723-01 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. The method is an adaptation of the diphenylcarbohydrazide method. The reaction between chromium VI and the reagent causes a purple tint in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible photometer can be used to determine the concentration from the color that is produced. The results will be displayed in μg/L (ppb) of chromium VI. These reagents are designed to be used with samples that have an expected range of 0 to 1000 μg/L chromium VI.
