Scope

This standard specifies the gas chromatography-mass spectrometry method for determining the concentrations of ten halogenated hydrocarbons, including trifluoromethane (HFC-23), dichlorodifluoromethane (HFC-32), pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a), dichlorodifluoromethane (CFC-12), monochlorodifluoromethane (HCFC-22), 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1-chloro-1,2,2,2-tetrafluoroethane (HCFC-124), and 1-chloro-1,1-difluoroethane (HCFC-142b) in gaseous refrigerants. This standard applies to the determination of the volume fraction of HFC-23, HFC-32, HFC-125, HFC-143a, CFC-12, HCFC-22, HFC-134a, HFC-152a, HCFC-124, and HCFC-142b in gaseous refrigerants, but is not applicable to the determination of the purity of these compounds. When the sampling volume is 20.0 μL, the method detection limits for the ten halogenated hydrocarbons range from 0.08% to 0.09%, and the determination limits range from 0.32% to 0.36%. For details, please refer to Appendix A.
