Cumene
Analysis:
Cumène
Method: IRSST - 159-1
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 (%):
2.2
Minimum reported value:
9 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 5.2%.

Following the amendment of Appendix 1 of the Quebec Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13), part of Quebec Occupational Health and Safety Act, which came into effect on March 26, 2020, the TWAEV, STEL and Ceiling values for certain substances are now expressed in
ppm
. For these substances, the IRSST performed the conversion calculations to express these TWAEV, TWA and Ceiling values in mg/m
3
, which thus appears in its Sampling Guide for Air Contaminants in the Workplace
(Guide d'échantillonnage des contaminants de l'air en milieu de travail )
and the associated Substance Data Sheets. However, it is imperative to refer to the values expressed in the RSST which are legally binding.
