About ArsenicAbout Arsenic49 of the 50 states have reported finding arsenic in waterEPA lowered the MCL (maximum containment level) to 10ug/L (PPB) Testing for arsenic below 10ug/L can be done by an analytical lab or by an on-site test kit quickly and accurately

How the Onsite Arsenic Kit worksHow the Onsite Arsenic Kit worksReduces inorganic arsenic (trivalent and pentavalent arsenic) in an acidic aqueous sample to arsine gasExcess hydrogen gas is generated, which facilitates the passage of the arsine gas through the reaction test strip which forms a yellow color in the presence of arsine directly proportional to the arsenic level

Tartaric acid is used to replace hydrochloric or sulfuric acids to remove hazardous reagents

The analysis is done with a 500 ml sample in a closed reaction bottle (plastic), which minimizes arsine gas hazards.

Test procedure for the Test procedure for the Ultra Low Arsenic Quick II Ultra Low Arsenic Quick II

STEP 1STEP 1For best results, the water temperature should be between 22°C to 28°C. Use a thermometer to verify the temperature of the sample.

To the Reaction Bottle, slowly add the water sample to the marked line on the bottle (500mL).

STEP 2STEP 2Add 2 level pink spoons of first reagent (tartaric acid with iron and zinc catalysts) to the reaction bottle. Cap securely with the black cap and shake vigorously for 15 seconds.


STEP 3STEP 3Uncap the reaction bottle and add 2 level red spoons of the second reagent (MPS which oxidizes sulfide).


STEP 4STEP 4Recap securely with the black cap and shake vigorously up and down for 15 seconds. Allow to sit for 2 minutes (this allows oxidation of sulfide).


STEP 5STEP 5Prepare the turret cap as follows: Open the packet and carefully remove the strip. Avoid touching the Mercuric Bromide testing pad. Position the testing pad over the orifice and press down the turret handle over the pad until it locks into position on the cap.


STEP 6STEP 6Uncap the Reaction Bottle and add 2 level white spoons of the Third Reagent (Zinc dust). Recap securely with the black cap and shake vigorously for 5 seconds.


STEP 7STEP 7Remove the black cap from the Reaction Bottle and recap securely using the turret cap with strip. Incubate for ten minutes.


STEP 8STEP 8After 10 minutes pull the turret up. Use the Color Chart (Quick™Ultra Low II) and match the color of the exposed side of the testing pad within 2 minutes.


The Quick™ Scan Test Pad Reader can be used as an alternative for determining the color intensity on the test strip.
