Cell Test
Measuring 0.20 – 5.00 mg/l Zn
range: Expression of results also possible in mmol/l.
Zinc
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Add 0.50 ml of the
sample with pipette,
close the cell with the
screw cap, and mix.
Add 5 drops of Zn-2K,
close the cell with the
screw cap, and mix.
Important:
For the determination of total zinc a pretreatment
with Crack Set 1
0C, Cat.No. 114688, or Crack Set 10,
Cat.No. 114687, and thermoreactor is necessary.
Result can be expressed as sum of zinc ( Zn).
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) w
e 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.
Check the pH of the
sample, specified range
:
pH 3 – 10.
If required, add dilute
sodium hydroxide
solution or hydrochloric
acid drop by drop to
adjust the pH.
