What is Molybdenum measured for?
Molybdenum (Mo) is used in water treatment as a corrosion inhibitor, especially in closed cooling circuits and heating systems. The correct dosage is crucial for effective corrosion protection while at the same time avoiding overdosing.
Depending on the type of system, typical target values are between 5 and 50 mg/l Mo. Photometric measurement enables precise monitoring of the dosage.
How does the test set work?
The CALDUR® Molybdenum test set is based on the thioglycolic acid method. The reagent forms a color complex with molybdenume, the concentration of which is precisely determined with the WINLAB Data Line photometer.

Areas of application
Carrying out the measurement:
- Fill water sample into round cuvette up to the mark
- Add reagent and mix
- Wait for 4 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 4 minutes
- For values above 100 mg/l: dilute the sample and convert the measured value
- Wipe the cuvette with a lint-free cloth before measuring
- Requires WINLAB Data Line Photometer (sold separately)
