Arsenic Quick was designed to give the user accurate results without
sacrificing cost and time. Designed using cutting-edge chemistry, Arsenic Quick
reports results in only 12 minutes. Additionally, there are no dangerous
chemicals needed to run this kit. With only one simple test procedure (using 3
reagents), Arsenic Quick is a must for any lab, water testing professional, or
service technician who values accurate, rapid results without sacrificing cost.
- Sensitivity: 0, 5, 10, 20, 50, 100, 200, >500 ppb (μg/L)
- Total test time: 12 minutes
Inorganic Arsenic compounds in the water sample are converted to Arsine
(AsH3) gas by the reaction of Zinc Dust and Tartaric Acid. Ferrous and Nickel
salts have been added to accelerate this reaction. The Arsine converts the
Mercuric Bromide on the test strip to mixed Mercury halogens (such as AsH2HgBr)
that appear with a color change from white to yellow or brown. Potassium
Peroxymonosulfate is added to oxidize Hydrogen Sulfide to Sulfate.
For better accuracy, we recommend running the test in duplicate for each
water sample.
1. For best results, verify that the water temperature is between 68° to 86°
F (ideally 71.6° to 82.4° F).
2. To the Reaction Bottle, slowly and carefully add the water sample to the
upper marked line on the bottle (100 mL).
3. Add 3 level pink spoonfuls of First Quick TM Reagent to the Reaction Bottle.
Cap bottle securely with yellow mixing cap and shake vigorously with bottle
upright for 15 seconds.
4. Uncap Reaction Bottle; add 3 level red spoonfuls of the Second Reagent. Cap bottle securely with yellow mixing cap and shake vigorously with
bottle upright for 15 seconds.
This step allows the test to tolerate Hydrogen Sulfide (H2S) up to 2ppm (mg/L).
If you suspect the presence of H2S by smell or testing, allow the sample to sit
for 2 minutes to minimize H2S interference before proceeding to Step 5.
5. Uncap Reaction Bottle and add 3 level white spoonfuls of Third Reagent. Cap bottle securely with yellow mixing cap and shake vigorously with
bottle upright for 5 seconds.
6. Remove yellow mixing caps. Recap bottles securely using white reaction caps
with turret up (open).
7. Remove Arsenic test strips from the test strip bottle. Immediately recap
the test strip bottle. In order for the results to be accurate, the test strip
must be oriented correctly, and inserted to the correct depth.
Insert the test strip into the turret:
- Position the strip so that the test pad and red line are facing the back of
the white reaction cap.
- Insert the strip into the turret until the red line is even with the top of
the turret, and close (flip down) the turret. This will hold the test strip in
place.
8. Using a timer, time the reaction for 10 minutes. Allow the reaction to occur
in an undisturbed, well-ventilated area. You will notice small hydrogen gas
bubbles being generated.
9. After the 10 minute wait, pull up the turrets and carefully remove the test
strip. Do not touch the reaction pads. Use the Easy-Read Color Chart to
match the reaction pad color. Position the reacted test strip pad behind the
punched holes, view center of test strip pad through the hole, and confirm
precise color match and Arsenic level.
Complete matching within the next 30
seconds. After 30 seconds have elapsed, the colors may begin to change. For best
color matching results, use natural daylight; avoid direct sunlight.
NOTE: If your Arsenic level is 200 ppb or above, you can confirm the elevated
levels by diluting the water sample 1 to 5. Fill the Reaction Bottle to the
bottom marked line with water sample (20 mL) and add Arsenic-free water to the
upper marked line. Now run steps 3 thru 10. For your true Arsenic value,
multiply the result by 5 to correct for dilution and record the value.
WARNING: Hydrogen and Arsine gases are generated during the test. Work in a
well-ventilated area away from open flames and other sources of ignition. Review
the Material Safety Data Sheet before handling any chemicals.
