Analysis:

Alcool propylique normal

Method: IRSST - 415
Sampling device:
Sampling media required:
#IRSSTDescription
2197 Anasorb 747 tubes (2) 400/200 mg in series

Parameters:
Flow rate: 0,05 L/min
TWA sampling volume: 12 L
STEL sampling volume: -
Remarks: At the end of sampling, the front tube must be separated from the back tube to avoid migration. Reseal each end of the tubes. Additional information is also available in french in "consigne d'utilisation I-MAT-039". n-Propyl alcohol must be sampled specifically because of the sampling device used.
Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision (%): 0,6
Minimum reported value: 60 µg
Remarks: However, simultaneous sampling and analysis of Methyl alcohol, Ethyl alcohol, Isopropyl alcohol, n-Butyl alcohol, Isobutyl alcohol and Sec-Butyl alcohol is possible.

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/m3, 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.
