What is aluminum measured for?
Aluminum (Al) enters the water through natural weathering and as a flocculant (aluminum sulfate). The limit value for drinking water is 0.2 mg/l Al (Drinking Water Ordinance). Elevated values may indicate faulty flocculation in the water treatment process.
The photometric measurement with the WINLAB Data Line Photometer enables precise determination of even low concentrations and is particularly suitable for process optimization in waterworks.
How does the test set work?
The CALDUR® Aluminum test set is based on a colorimetric complexation reaction. After adding three reagents to the water sample, a coloration develops within 8 minutes, the intensity of which is precisely determined using the WINLAB Data Line photometer.
Advantages of the CALDUR® test set
- Sensitive measuring range 0.02 – 0.3 mg/l Al
Ideal for drinking water monitoring and flocculation control
- 100 provisions per set
Economical for regular checks
- High precision due to photometric evaluation
Objective, reproducible measurement results with the WINLAB Data Line
- Easy handling with 3 reagents
Clear step-by-step instructions
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 8 minutes reaction time
- Insert the cuvette into the WINLAB Data Line photometer and start the measurement
Important notes
- Adhere exactly to the response time of 8 minutes
- Sample must not be turbid – filter beforehand if necessary
- Wipe the cuvette with a lint-free cloth before measuring
- Requires WINLAB Data Line Photometer (sold separately)
