1 Scope of application
This standard specifies the determination of trifluoromethane (HFC-23), difluoromethane (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 10 kinds of halogens including HFC-152a, 1-chloro-1,2,2,2-tetrafluoroethane (HCFC-124) and 1-chloro-1,1-difluoroethane (HCFC-142b) Gas Chromatography-Mass Spectrometry of Substituted Hydrocarbons.
This standard applies to 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. The determination is not suitable for the determination of the purity of the above-mentioned compounds.
When the sampling volume is 20.0 μl, the detection limit of the method for 10 halogenated hydrocarbons is 0.08%～0.09%; the lower limit of determination is 0.32%～0.36%. See Appendix A for details.
