Monitoring of ozone-depleting substances takes place in global climate policy. To ensure accounting of used and transported ozone-depleting substances, it is necessary to develop high spectral identification systems. Multicomponent refrigerants with a high ozone-depleting potential and a potential for global warming are considered as ozone-depleting substances. The features of refrigerants as objects of research are described. Based on the characteristics of refrigerants, such identification methods as chromatography-mass spectrometry, absorption spectroscopy and Raman spectroscopy were reviewed. Comparative analysis of refrigerant identification methods has been performed. According to the results of the data obtained in the analysis of refrigerants, the Raman spectroscopy method was chosen as the most selective one. The block-diagram for the identification system for ozone-depleting substances was proposed and experimental studies of the refrigerant R-22 were carried out.
