Consult REPTOX file:
2,4,6-Trinitrotoluene (TNT)(IFV)
Analysis:
Trinitro-2,4,6 toluène (TNT)
Recommended method by the IRSST:
Method: OSHA - 44
Sampling protocol
Sampling device:
Tenax-GC tube with a glass fiber filter
Parameters:
Flow rate: 1 L/min
TWA sampling volume: 60 L
STEL sampling volume: -
Remarks:
The recommanded method for 2,4,6-Trinitrotoluene is suitable for both vapor and aerosol phases. The aerosol phase might be underestimated because the efficiency of the sampling device does not match inhalable fraction definition. For more information, please contact the IRSST. This substance is not analyzed by our laboratories. It might be possible that the analysis is performed by another laboratory. Please contact the IRSST before sampling.
Analytical protocol
Principle:
Gas chromatography with electron-capture detection (GC-ECD)
