Using the LaMotte Cyanide in Water Test Kit, the cyanide is first reacted with a chlorine donor to form cyanogen chloride, which then reacts with pyridine-barbituric acid to form a red-blue color. Levels are determined using the Octa-Slide 2 comparator.

This Biological Activity Reaction Test tests for heterotrophic aerobic bacteria. Test kit includes nine tests. The change of blue color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
