MACHEREY-NAGEL visocolor ECO Copper Test Tube
Test kit for performing colorimetric tests on copper ions in surface water and sewage
Method:
Combined with cuprizone [oxalic acid bis(cyclohexylidene hydrazide)],
copper(II) ions form a blue complex in the alkaline range.
Measurement range
- 0.1–1.5 mg/L Cu2+
*Contents (refill pack):**
sufficient for 100 tests
- 30 mL Cu-1*
- 20 mL Cu-2*
- 2 screw-plug measuring glasses
- 1 slide comparator
- 1 color chart
- 1 plastic syringe 5 mL
- 1 instruction for use*
Hazard warning:
Information regarding safety can be found on the box’ label and in the safety
data sheet. You can download the SDS from www.mn-net.com/SDS.
Instructions for use
also refer to the pictogram on the back of the color chart
- Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe. Place a measuring glass on position A in the comparator. Only add the reagent to measuring glass B.
- Add 5 drops of Cu-1, seal the glass and mix.
- Add 5 drops of Cu-2, seal the glass and mix.
- Open the glass after 10 min and place it on position B in the comparator.
- Slide the comparator until the colors match in the inspection hole on top. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
- After use, rinse out both measuring glasses thoroughly and seal them.
The reagents can be used for the photometric evaluation with photometers PF-12 / PF-12Plus / Advance. This technique can be used also for analyzing sea water.
Disposing of the samples:
Information regarding disposal can be found in the safety data sheet. You can
download the SDS from www.mn-net.com/SDS.
Interferences:
Strongly acidic and buffered test samples are to be adjusted to pH 9 with
ammonia before determination. Iron(II), chromium(VI), nickel and manganese
ions disrupt tests if they are present in concentrations in excess of 10 mg/L.
Chromium(III) ions present in concentrations in excess of 10 mg/L cause
clouding and lead to limited results. Cobalt ions form a red color complex
and, depending on the concentration of copper, disrupt the tests if present in
concentrations from as little as 1 mg/L. If cyanide and sulfide are present in
concentrations in excess of 1 mg/L, they will lead to limited results.

Storage:
Store the test kit in a cool (< 25 °C) and dry place.
