GB/T 18826-2016--Porapak Q 1,1,1,2-四氟乙烷中不凝性气测定填充柱

R134a是目前国际公认的CFC-12 的主要制冷工质之一，HFC-134a不含氯原子，对大气臭氧层不起破坏作用；具有良好的安全性能（不易燃，不爆炸，无毒，无刺激性，无腐蚀性）；在常温下为无色气体，在自身压力下为无色透明液体，是R12 的替代品。常用于汽车空调，商业和工业用制冷系统，以及作为发泡剂用于硬塑料保温材料生产，也可以用来配置其他混合制冷剂，如R404a和R407c等。

浩瀚色谱（山东）应用技术开发有限公司，依据工业1,1,1,2-四氟乙烷的要求，测定了不凝气的含量，柱效高，分离好，结果满意。

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.
