Here's how it works:
First, your water sample is mixed in the supplied reaction vessel with reagent #1 (Tartaric acid with rate enhancers). This will acidify your water sample. Reagent #2, an oxidizer, is then added to remove hydrogen sulfide interference. Finally, with the addition of Zinc powder, reagent #3, 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 is generated and comes in contact with the test strip, the Mercuric bromide indicator on the test strip changes in color from white to shades of yellow or brown. Once the reaction is completed, the test strip is removed and matched to a calibrated color chart to obtain a quantitative measure of arsenic in the tested sample.
