Methyl propyl ketone
Analysis:
Méthyl propyl cétone
Method: IRSST - 178-1
Sampling protocol
Sampling device:
Sampling media required:
#IRSST
Description
2120
Activated charcoal tube 100/50 mg
Parameters:
Flow rate: Max: 0,2 L/min
TWA sampling volume: 10 L
STEL sampling volume: -
Analytical protocol
Principle:
Gas chromatography with flame ionization detection (GC-FID)
Precision (%):
2,0
Minimum reported value:
110 µg
Remarks:
The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 6.8%.
