CNESST – Toxicological Index Service
Consult REPTOX file:
Caprolactam(IFV)
Analysis:
Caprolactame
Recommended method by the IRSST:
Method: OSHA - PV2012
Sampling protocol
Sampling device:
OVS-7 tube with XAD-7 and glass fiber filter
Parameters:
Flow rate: 1 L/min
TWA sampling volume: 100 L
STEL sampling volume: 15 L
Remarks:
The recommanded method for Caprolactame 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.
Analytical protocol
Principle:
High performance liquid chromatography with UV detection (HPLC-UV)
