About ArsenicAbout Arsenic
49 of the 50 states have reported finding
arsenic in water
EPA 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 works
Reduces inorganic arsenic (trivalent and
pentavalent arsenic) in an acidic aqueous
sample to arsine gas
Excess 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

The kit was assessed for
reliability for on-site
Arsenic water testing.

The reduction in all these kits utilizes zinc
and includes the following reactions:
AsAs44OO66 + 12 Zn +24H+ 12 Zn +24H++

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 theTest procedure for the
Ultra Low Arsenic Quick IIUltra Low Arsenic Quick II
STEP 1STEP 1
For 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 2
Add 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 3
Uncap the reaction
bottle and add 2 level
red spoons of the
second reagent (MPS
which oxidizes
sulfide).

STEP 4STEP 4
Recap 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 5
Prepare 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 6
Uncap 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 7
Remove the black
cap from the Reaction
Bottle and recap
securely using the
turret cap with strip.
Incubate for ten
minutes.

STEP 8STEP 8
After 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.
