eXact Complete Cyanide Visual Test Kit, No Meter (50 tests/set)

The test procedure is as follows: add 2 ml sample to microcuvette, dip #1 ReagentStrip™ (adjusts the pH of the sample and converts cyanide to cyanogens chloride) for 30 seconds into sample, then dip #2 ReagentStrip™ (cyanogen chloride reacts with Isonicotinic and Dimethybarbituric acids to for a blue color) for 30 seconds. View #2 ReagentStrip™ for blue color to determine semi-quantitative concentration. After 10 minutes match color in cuvette to color chart for quantitative cyanide concentration. Color reading can also be made using a colorimeter or spectrophotometer for more precise determination. Detection sensitivity is 0.01 PPM (mg/L), with a range to 1.0 PPM. The DPD ReagentStrip™ Cyanide Kit is the quick and accurate solution for testing cyanide concentrations.
