Nitroethane
Analysis:
Nitroéthane
Recommended method by the IRSST:
Method: NIOSH - 2526
Sampling protocol
Sampling device:
Two XAD-2 tubes in series
Parameters:
Flow rate: 0,01-0,05 L/min
TWA sampling volume: 3 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. Contact the IRSST before sampling.
Analytical protocol
Principle:
Gas chromatography with flame ionization detection (GC-FID)
