Test
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) ready-f
or-use
cadmium standard solution Certipur
®
, Cat.No. 119777,
concentration 1000 mg/l Cd, can be used after diluting
accordingly.
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.
