MACHEREY-NAGEL Visocolor ECO Chloride Colorimetric Test Kit Range
Test kit for performing colorimetric tests on chloride ions in surface water and sewage
Method:
Chloride ions react with mercuric thiocyanate to produce undissociated
mercuric chloride and to liberate thiocyanate ions. In the presence of ferric
salts this thio- cyanate ions produce a characteristic orange color
Measurement range:
1–60 mg/L Cl–
Contents ot test kit (*refill pack)
sufficient for 90 tests
- 2 x 20 mL Cl-1*
- 24 mL Cl-2*
- 2 screw-plug measuring glasses
- 1 slide comparator
- 1 color chart
- 1 plastic syringe 5 mL
- 1 instructions 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 one measuring glass on position A in the comparator. Only add the reagents to measuring glass B.
- Add 10 drops of Cl-1. Seal the glass and mix.
- Add 10 drops of Cl-2. Seal the glass and mix.
- Open the glass after 1 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 (see „Disposal“) and seal them.
The method can not be applied for the analysis of sea water.
Measurement up to 300 mg/L chloride
- Pour a 1 mL water sample and 4 mL of distilled water into each of the mea- suring glasses.
- Same procedure as described above. Multiply the read-off value by 5 (see „Conversion table“).
Conversion table for measurements up to 300 mg/L chlorides:
- Read-off value in mg/L Cl– Chloride concentration in
- mg/L Cl– (read-off value x 5)
- 1 5
- 2 10
- 4 20
- 7 35
- 12 60
- 20 100
- 40 200
- 60 300
The reagents can be used for the photometric evaluation with photometer PF-12
/ PF-12Plus.
Disposal:
Information regarding disposal can be found in the safety data sheet. You can
download the SDS from www.mn-net.com/SDS.
Interferences:
Bromide, cyanide, iodide, sulfide, thiocyanate and thiosulfate all interfere
since they react in the same way as chloride. The following ions will not
interfere: ≤ 2000 mg/L NO2 ; ≤ 20 mg/L F–.
Note:
For the determination of chloride in concrete, please contact MACHEREY-NAGEL
for special working instructions.
Storage:
Store the test kit in a cool (< 25 °C) and dry place.
