Notes:
1. Before use, clean the vials and the accessories with Hydrochloric acid (approx. 20%).
Rinse them thoroughly with deionised water.
2. To get accurate results the sample temperature must be between 20°C and 25°C.
3. A low test result may be given in the presence of Fluorides and Polyphosphates. The
effect of this is generally insignificant unless the water has fluoride added artificially.
In this case, the following table should be used:
Fluoride
[mg/l F] Displayed value: Aluminium [mg/l Al]
0.05 0.10 0.15 0.20 0.25 0.30
0.2 0.05 0.11 0.16 0.21 0.27 0.32
0.4 0.06 0.11 0.17 0.23 0.28 0.34
0.6 0.06 0.12 0.18 0.24 0.30 0.37
0.8 0.06 0.13 0.20 0.26 0.32 0.40
1.0 0.07 0.13 0.21 0.28 0.36 0.45
1.5 0.09 0.20 0.29 0.37 0.48 ---
Example: If the result of Aluminium determination is 0.15 mg/l Al and the Fluoride
concentration is known to be 0.4 mg/l F, the true concentration of Aluminium is
0.17 mg/l Al.
4. A special tablet ingredient prevents effects on the measurement due to iron and
manganese.
