•Ideal for field water testing.
•Designed to detect inorganic arsenic (As+3 and As+5).
•US EPA test verified performance.
•Procedure includes only three simple steps.
•Test kits are easy-to-use, safe, fast and sensitive.
•No dangerous chemicals needed.
•Yield results in less than 14 minutes.
•Procedure: First, water sample is mixed with Reagent #1 (tartaric acid with rate enhancers) in supplied reaction bottle in order to acidify. Then, Reagent #2 (an oxidizer) is added to remove hydrogen sulfide interference. Finally, Reagent #3 (zinc powder) is added and inorganic arsenic compounds (As+3 and As+5) are reduced to arsine gas. A test strip is used to measure the arsine gas concentration in the water sample. As arsine gas comes in contact with the test strip, the mercuric bromide indicator on the test strip changes from white to yellow or brown. Match test strip to a calibrated color chart to obtain a quantitative measure of arsenic concentration in the tested sample.
•Test procedures are also available for testing arsenic in soil and urine.

* Soil analysis procedure included.
