Arsenic (Individual Test Kits)
Arsenic: The procedure requires about 15 minutes and employs a test strip. Inorganic As+3 and As+5 are converted to arsine gas. This reacts with the test strip in a closed container and produces yellow to brown colors on the strip. The strip color is compared to a color chart to determine concentration in ppb. Recommended for high school and university use only. Teacher supervision required.
