Isobutyl alcohol
Analysis:
Alcool isobutylique
Method: IRSST - 278-1
Sampling protocol
Sampling device:
Sampling media required:
#IRSST
Description
2120
Activated charcoal tube 100/50 mg
Parameters:
Flow rate: Max: 0.2 L/min
TWA sampling volume: 10 L
STEL sampling volume: -
Analytical protocol
Principle:
Gas chromatography with flame ionization detection (GC-FID)
Precision (%):
6,4
Minimum reported value:
75 µg
Remarks:
The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 7.6%.

Isobutyl alcohol
Method: IRSST - 415
Sampling protocol
Sampling device:
Sampling media required:
#IRSST
Description
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". Isobutyl alcohol must be sampled specifically because of the sampling device used.
Analytical protocol
Principle:
Gas chromatography with flame ionization detection (GC-FID)
Precision (%):
0,5
Minimum reported value:
30 µg
Remarks:
However, simultaneous sampling and analysis of Methyl alcohol, Ethyl alcohol, sec-Butyl alcohol, n-propyl alcohol, Isopropyl alcohol and n-Butyl alcohol is possible.

STEL sampling volume: -
Remarks:
For the monitors, the flow must be considered as being a sampling rate.
Analytical protocol
Principle:
Gas chromatography with flame ionization detection (GC-FID)
Precision (%):
2,7
Minimum reported value:
8 µg
