examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable dam-
age, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:

• HI 93702-0 Reagent, packets (50 pcs);
• HI 3856-0 Reagent, packets (50 pcs);
• Deionized Water, 1 bottle (230 mL)
• 1 long path color comparator cube;
• 1 color comparator cube;
• 1 plastic test tube (14 mL) with screw cap;
• 1 plastic pipette (3 mL).

SIGNIFICANCE AND USE

CHEMICAL REACTION

Copper salts react with bicinchoninate reagent to form a
purple product in a neutral buffered condition. The amount
of color developed is proportional to the concentration of
copper present in the aqueous sample.

Copper is an essential trace element in human diet (the

daily requirement is around 2.0 mg) and a factor in plant
metabolism. Copper salts are used in water supply systems
to control biological growth in reservoirs. High concentrations
on the other hand are toxic and corrosion of copper alloys in
pipe fittings may introduce considerable quantities into the
water supplies.
Note: mg/L is equivalent to ppm (parts per million).

INSTRUCTIONS

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• To measure copper in the 0-0.25 range, fill the long

path comparator cube with sample up to the 25 mL
mark.

The chemicals contained in this kit may be hazardous if
improperly handled. Read the relevant Health and Safety

Data Sheet before performing this test.

HEALTH AND SAFETY

REFERENCES

Adaptation of EPA approved method.

• Add 1 packet

of HI 3856-0

reagent.

• Replace the cap and mix by

inverting the cube several times.

• Wait 45 seconds to allow color to

develop.

• Determine which

color best matches
the solution in the

cube and read
the result directly
in mg/L (ppm) of
Copper.

• It is better to

match the color
with a white
sheet placed at

about 10 cm (4") behind the comparator.

• To measure copper in the 0-6.0

range, use the pipette to fill the
plastic test tube with 2.5 mL of
sample, up to the mark.

• Add 3.5 mL of

Deionized Water to
reach the 6 mL
mark. Replace the
cap and swirl to
mix. This is the
diluted sample.

• Pour then 5 mL of the di-

luted sample from the tube
to the color cube (up to the

mark).

• Add 1 packet of HI 93702-0, replace

the cap and shake well.

• Wait 45 seconds to

allow color to develop.

• Determine which color matches the solution in the vessel.

Multiply the result by 2.4 to obtain mg/L (or ppm) of
Copper in the sample.

• It is better to match the color with a white sheet placed

at about 10 cm (4") behind the comparator.
