Cell Test
Measuring 0.025 – 1.000 mg/l Cd
range: Expression of results also possible in mmol/l.
Cadmium
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 30, Cat.No. 114677.
Ready-for-use cadmium standard solution Certipur
®
,
Cat.No. 119777, concentration 1000 mg/l Cd, can also
be used after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 30) is highly recommended.
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.
Result can be expressed as sum of cadmium (
 Cd).
Check the pH of the
sample, specified range
:
pH 3 – 11.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
Pipette 5.0 ml of the
sample into a reaction
cell, close with the
screw cap, and mix.
Add 0.20 ml of Cd-1K
with pipette, close the
cell with the screw cap,
and mix.
Add 1 level green
microspoon of Cd-2K,
close the cell with the
screw cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
Reaction time:
2 minutes
