Results in just 10 minutes.
Diagrammed instructions and distinct color standards make this test easy to perform. Plus, the 10-minute reaction time means you get results fast.
Procedure detects inorganic As
+3 and As
+5 by converting these to arsine gas, which produces a yellow to brown color on a test strip. Just compare the test strip to the color standards to determine the arsenic concentration.
