Cat.No. 116754  Water for analysis
 
Measuring range:
1.0 - 15.0 mg/l calcium in a 10-mm cell at 550 nm.
 
Procedure:
To 1 ml sample add 10 ml of reagent Ca-1 and mix. Add 8 drops of reagent Ca-2 and Ca-3 and mix.
For the blank reading treat 1 ml of water for analysis in the same way as the sample.
 
Analyse:
Determine by means of photometer; the method is already programmed in the instruments.
