Cat.No. 114554  Spectroquant® Nickel Cell Test
Cat.No. 114785  Spectroquant® Nickel Test
Cat.No. 116754  Water for analysis
 
Sample preparation:
In a 500-ml standard volumetric flask place 2.5 ml of bath solution, which has been cooled to room temperature, fill up to volume with water for analysis and mix well. Take from this solution a further 5 ml and place in a second 500-ml standard volumetric flask and again fill up with water for analysis and mix.
Determine readily the nickel content in solutions diluted in this fashion.
 
Analysis:
Determine with the above mentioned test kits
 
Calculation:
Nickel content in g/l = analysis value in mg/l Ni x 20
