Industrial Test Systems 481298 Arsenic Econo-Quick, 300 Tests

Arsenic Econo-Quick is ideal for field and lab technicians who do a large volume of tests and time is valuable. With accurate results in only 12 minutes, Arsenic Econo-Quick uses a simple 3-step reagent system that minimizes exposure to chemicals and maximizes the use of your time. With results comparable to high-end ICP testing methods, at a fraction of the cost, Arsenic Econo-Quick only requires a 50mL sample size to run. Quick Arsenic tests were developed with considerations for safety, sensitivity, ease-of-use and speed.

Features:

• Results in only 12 minutes
• Reagents are clearly labeled and color-coded
• A colorimetric test strip is used to take the guesswork out of accurate arsenic measurement
• Includes an easy-read color chart, which makes matching simple
• All reagents are in powder form and have been carefully selected to minimize the hazards associated with conventional arsenic testing
• All components needed to accurately detect and measure arsenic are included in a portable ready-to-use kit

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, 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.
