Composition Analysis of Contaminated and Counterfeit Refrigerants Using the Agilent 490 Micro

Version 7

    Application Note

    Micro Gas Chromatography, Refrigerant Analysis, Product Quality



    The importance of refrigerant composition analysis became clear when contaminated and counterfeit refrigerant 1,1,1,2-tetrafluorethane (R134a) appeared on the market. Chloromethane (R40), present in this counterfeit R134a, is found to be incompatible with aluminum surfaces in the refrigerant system. A chemical reaction takes place resulting in a pyrophoric compound upon contact with air. This application note highlights fast, on-site characterization of the refrigerant mixture using the Agilent 490 Micro GC.
