Analysis:

Perchloroéthylène

Method: IRSST - 140-2

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: 3 L

Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision (%): 7,3
Minimum reported value: 68 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 3.6%.
