Analysis:
Chrome Solu-Sert
Method: IRSST - 426
Sampling protocol
Sampling device:
Sampling media required:
#IRSST
Description
990
25-mm Solu-Sert MCE filter
Parameters:
Flow rate: 1.5 L/min
TWA sampling volume: 180 L
STEL sampling volume: -
Remarks:
A surface wipe sampling is available. For more information, please contact the IRSST.
Analytical protocol
Principle:
Inductively coupled plasma spectrometry (ICP-MS)
Precision (%):
3,6
Minimum reported value:
3,6 µg
Remarks:
This method allows the analysis of chemical elements present in the sample without distinguishing the different chemical forms. The analytical results are expressed as total chormium.
