Arsenic Low Range Quick™ II for water quality testing was designed to give
the user accurate results without sacrificing cost and time. Designed using
cutting-edge chemistry, Arsenic Low Range Quick™ II reports results in only 14
minutes. Additionally, there are no dangerous chemicals needed to run this water
quality test kit. With only one simple test procedure (using 3 reagents),
Arsenic Low Range Quick™ II is a must for any lab, water testing professional,
or service technician who values accurate, rapid results without sacrificing
Safety has not been compromised for convenience in the Arsenic Quick™ family
of arsenic field test kits. 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.
Our easy to follow test procedure requires only three reagents and as little as
12 minutes to perform. Reagents are clearly labeled and color coded to make
arsenic testing error free. A colorimetric test strip is used to take the
guesswork out of accurate arsenic measurement. The matching color chart is
thoughtfully printed with extra large color blocks and contrasting colors for
quick and accurate determinations.
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.
The patented (6,696,300) and patent pending test kits have five formats
available to suit any testing requirement. Our standard Arsenic Quick™ test kit
detects 5 ppb (μg/L) of arsenic in 12 minutes. For added sensitivity, use the
Low Range Arsenic Quick™ kit to detect arsenic concentrations of 2 ppb (μg/L) in
12 minutes. The Arsenic Econo-Quick™ kit is our latest addition with 300 tests
per kit at a low price and a detection level of 10 ppb (μg/L) with a quick 12
minute test time. For single use, retail sale, and evaluation, a 2-test Arsenic
Quick™ kit is also offered.
