Packed column for determination of non-condensable gas in 1,1,1,2-tetrafluoroethane

Details of packed column for determination of non-condensable gas in 1,1,1,2-tetrafluoroethane:



R134a is currently internationally recognized as one of the main refrigerants of CFC-12. HFC-134a does not contain chlorine atoms and does not damage the atmospheric ozone layer; It has good safety performance (nonflammable, non-explosive, non-toxic, non-irritant, non-corrosive); It is a colorless gas at normal temperature and a colorless transparent liquid at its own pressure. It is a substitute for R12. It is often used in automobile air conditioners, commercial and industrial refrigeration systems, as well as in the production of rigid plastic insulation materials as a foaming agent, and can also be used to configure other mixed refrigerants, such as R404a and R407c.



Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has determined the content of non-condensable gas according to the requirements of industrial 1,1,2-tetrafluoroethane, with high column efficiency, good separation and satisfactory results.
