Multy
Pipette 1.0 ml each of
Cd-1 into two 24-mm
cells.
Add to one cell 10 ml of
the sample with pipette,
close with the screw
cap, and mix.
Add to each cell 0.20 ml
of Cd-2 with pipette,
close with the screw
cap, and mix.
Measuring range: 5 – 500 µg/l Cd
24-mm cell
Add to each cell 1 level
green microspoon of
Cd-3, close with the
screw cap, and dissolve
the solid substance.
Cadmium

Test
Add to the second cell
10 ml of distilled water
with pipette, close with
the screw cap, and mix.
(Blank cell)
Select method 1 0 1 .
Insert the cell containing
the sample into the cell
compartment. Align the
mark on the cell with
that on the photometer.

Reaction time:
2 minutes
Press Enter to start
the countdown.
Check the pH of the
sample, specified range:
pH 3 – 11.
If required, add dilute

the pH.
Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) ready-for-use cadmium
standard solution Certipur
®
, Cat.No. 119777, concentra-
tion 1000 mg/l Cd, can be used after diluting accordingly.
The measurement results are expressed in µg/l.
Important:
For the determination of total cadmium a pretreatment
with Crack Set 10C, Cat.No. 114688 or Crack Set 10,
Cat.No. 114687, and thermoreactor is necessary.
Insert the blank cell into
the cell compartment.
Align the mark on the
cell with that on the pho-
tometer. Press Zero .
