Consult REPTOX file: Diethlene glycol monobutyl ether

Analysis:

Diethlene glycol monobutyl ether

Method: IRSST - 404

Sampling protocol

Sampling device:
Sampling media required:

#IRSST	Description
2120	Activated charcoal tube 100/50 mg

Parameters:
Flow rate: 0.2 L/min
TWA sampling volume: 10 L
STEL sampling volume: -
Remarks: The analysis of Diethylene glycol monobutyl ether (CAS 112-34-5) must be sampled specifically due to a specific desorption solvent.

Analytical protocol

Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision (%): 4.0
Minimum reported value: 30 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 monomethyl ether (CAS 109-86-4), propylene glycol monomethyl ether (CAS 107-98-2), 2-Methoxyethyl acetate (EGMEA) (110-49-6) and Ethylene glycol monoethyl ether (CAS 110-80-5) are possible.
