Cell Test
Measuring 0.10 – 6.00 mg/l Ni
range: Expression of results also possible in mmol/l.
Nickel
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) w
e recommended
to use Spectroquant
®
CombiCheck 40, Cat.No. 114692.
A nickel standard solution Titrisol
®
, Cat.No. 109989, can
also be used after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 40) is highly recommended.
Important:
For the determination of total nickel a pretreatment
with Cr
ack Set 10C, Cat.No. 114688, or Crack Set 10,
Cat.No. 114687 and thermoreactor is necessary.
Result can be expressed as sum of nickel (
Ni).
Check the pH of the
sample, specified range:
pH 3– 8.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
Add 2 drops of Ni-1K,
close with the screw
cap, and mix.
Reaction time:
1 minute
Pipette 5.0 ml of the
sample into a reaction
cell, close with the screw
cap, and mix.
Add 2 drops of Ni-2K,
close the cell with the
screw cap, and mix.
Reaction time:
2 minutes
