Detection of ozone-depleting substances and halogenated GHGs

China has phased out chlorofluorocarbons (CFCs) and is gradually phasing out hydrochlorofluorocarbons (HCFCs), while hydrofluorocarbons (HFCs), although not harmful to the ozone layer, have a potent greenhouse effect and were added to the Montreal Protocol in 2016. Markes International presents a quantitative analysis method for ozone-depleting substances (ODS) and halogenated greenhouse gases (GHGs) without cryogen, meeting detection limit and data quality requirements outlined by the China National Environmental Monitoring Centre. The analysis system includes a canister autosampler, water vapor removal device, thermal desorption instrument, and GC-MS analyzer in SIM mode, capable of monitoring samples with 100% relative humidity and analyzing 34 ODS and halogenated GHGs qualitatively and quantitatively.
