Oxyde d'éthylène

Method: IRSST - 39-A
Sampling device:
Parameters:
Flow rate: -
TWA sampling volume: -
STEL sampling volume: -
Remarks: Refer to the user's guide accompanying the instrument.
Principle: Direct reading instrument-Photoacoustic detection (DRI-PAD)
Remarks: Ethylene oxide is quantified in the field with a direct-reading instrument (DRI). The minimum reported value is 0.43 mg/m³ (0.24 ppm). The reference method corresponds to calibration of the DRI.
