Notes:
1. Before use, clean the vials and the measuring beaker 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 ef-
fect of this is generally insignificant unless the water has fluoride added artificially.
In this case, the following table should be used:
Fluoride
[mg/l
0.05
F]
0.2
0.05
0.4
0.06
0.6
0.06
0.8
0.06
1.0
0.07
1.5
0.09
Example: If the result of Aluminium determination is 0.15 mg/l Al and the Fluoride con-
centration 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 manga-
nese.
