Cat.No. 114767  Spectroquant® Copper Test
Cat.No. 107209  Hydrogen peroxide 30 % (Perhydrol®) for analysis
Cat.No. 116754  Water for analysis
Sample preparation:
Place 5 ml of the bath solution in a 500-ml volumetric flask and fill up to volume with water for analysis. Take
5 ml from this solution and fill up to 500 ml, with water for analysis, to give a 1:10000 dilution.
Pipet 10 ml of this final dilution into a test-tube, add 1 drop of Perhydrol®, mix and allow to stand for 1 minute. The further treatment is as given in the manual.
Determine with the above mentioned test kits
Copper (total) content in g/l Cu = analysis value in mg/l Cu x 10
