Analysis:
Thiram®
Recommended method by the IRSST:
Method: NIOSH - 5005
Sampling protocol
Sampling device:
Polytetrafluoroethylene (teflon) filter
Parameters:
Flow rate: 1-4 L/min
TWA sampling volume: 400 L
STEL sampling volume: -
Remarks:
The recommanded method for Thiram is suitable for the aerosol phase exclusively. 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:
High performance liquid chromatography with UV detection (HPLC-UV)
