What is manganese measured for?
Manganese (Mn) occurs naturally in groundwater and at high concentrations can lead to black deposits in pipes, discoloration and an unpleasant taste. The limit value for drinking water is 0.05 mg/l Mn (Drinking Water Ordinance).
In water treatment, manganese must be reliably monitored as it can pollute the filter systems. Photometric measurement enables precise determination over a wide concentration range.
How does the test set work?
The CALDUR® Manganese test set is based on the formaldoxime method. After adding three reagents to the water sample, an orange-red coloration develops within 10 minutes, the intensity of which is precisely determined with the WINLAB Data Line photometer.
Advantages of the CALDUR® test set
- Large measuring range 0.05 – 20 mg/l Mn
From the drinking water limit to high industrial concentrations
- 100 provisions per set
Economical for regular checks
- High precision due to photometric evaluation
Objective, reproducible measurement results with the WINLAB Data Line
- Proven formaldoxime method
Specific for manganese, little interference
Areas of application
Carrying out the measurement:
- Fill water sample into round cuvette up to the mark
- Add reagent A and mix
- Add reagent B and mix
- Add reagent C and mix
- Wait for 10 minutes reaction time
- Insert the cuvette into the WINLAB Data Line photometer and start the measurement
Important notes
- Adhere exactly to the reaction time of 10 minutes
- Sample must not be turbid – filter beforehand if necessary
- Wipe the cuvette with a lint-free cloth before measuring
- Iron in high concentrations can influence the result
- Requires WINLAB Data Line Photometer (sold separately)
