According to Decree 280-2024 published on February 28, 2024, in the Gazette officielle du Québec, the amendment to the Appendix 1 of the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) will come into force on March 14, 2024. These regulatory changes have not yet been incorporated into the current Substance Data Sheets of the Sampling Guide for Air Contaminants in the Workplace. An update is currently underway and will be available as soon as possible. Consequently, the information contained in the data sheets of substances modified or added in Decree 280-2024 is partially inaccurate or incomplete. Please consult our infoLABO (in French only) for more details. Please contact our client service: [email protected] for further information.

Éther monoéthylique de l'éthylène glycol

Method: IRSST - 137-1

Sampling protocol

Sampling device:
Sampling media required:
#IRSSTDescription
2120 Activated charcoal tube 100/50 mg

Parameters:
Flow rate: Max: 0,2 L/min
TWA sampling volume: 10 L
STEL sampling volume: -
Remarks: The analysis of Ethylene Glycol Monethyl Ether (CAS 110-80-5) must be sampled specifically due to a specific desorption solvent..

Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision (%): 4
Minimum reported value: 10 µg
Remarks: However, the simultaneous sampling and analysis of Ethylene Glycol Monobutyl Ether Acetate (CAS 112-07-2), Butoxy 2-ethanol (CAS 111-76-2), Ethylene Glycol Ether diethylene glycol and monobutyl (CAS 112-34-5), ethylene glycol monomethyl ether (CAS 109-86-4), propylene glycol monomethyl ether (CAS 107-98-2) and 2-Methoxyethyl acetate (EGMEA) (110-49-6) are possible.
