16-mm cell
Zinc
Add to one cell 0.50 ml
of the sample with pi-
pette, close with the
screw cap, and mix.
Add to each cell 5 drops
of Zn-2K, close with the
screw cap, and mix.
Add to the second cell
0.50 ml of distilled water
with pipette, close with
the screw cap, and mix.
(Blank cell)
Select method 5 4 1 .

Important:
For the determination of total zinc a pretreatment
with Crack Set 10C, Cat.No. 114688, or Crack Set 10,
Cat.No. 114687, and thermoreactor is necessary.
Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) we recommended to use
Spectroquant
®
CombiCheck 40, Cat.No. 114692.
Ready-for-use zinc standard solution
Certipur
®
, Cat.No.
119806, concentration 1000 mg/l Zn, 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.
Insert the blank cell into
the cell compartment.
Align the mark on the
cell with that on the pho-
tometer. Press Zero .
