工业用1,1,1,2-四氟乙烷(HFC-134a)中不凝气测定填充色谱柱
工业用1,1,1,2-四氟乙烷(HFC-134a)中不凝气测定填充色谱柱 详细信息:


制冷剂中的不凝性气体(NCG)主要是由液相制冷剂中原始空气积累起来的。制冷剂中含有过高的NCG会使制冷机械的参数发生变化,从而影响制冷效果。在和外商的业务往来中获悉,外商对制冷剂中NCG含量十分重视。


浩瀚色谱(山东)应用技术开发有限公司研发气相色谱法测定含氟烯烃中不凝性气体含量的方法,所述色谱条件为色谱柱:Porapak Q[(1~6)m×(1~7)mm)]填充柱等.提供的方法能够简便,准确,快速,,低成本的测定含氟烯烃气相中不凝性气体的含量.

1,1,1,2-Tetrafluoroethane as a pharmaceutical excipient for polymer porous microsphere filled column

Details of 1,1,1,2-tetrafluoroethane as a pharmaceutical excipient for the application of polymer porous microsphere filled column:






Pharmaceutical excipient tetrafluoroethane (HFC-134a)





1、 Basic information



Product name: medicinal excipient 1,1,1,2-tetrafluoroethane



Molecular formula: CH2FCF3



Relative molecular weight: 102.03



Product standard: G/JHGF O1 J 20 209-2012



2、 Physical and chemical properties: it is a colorless gas with slight ether odor under normal temperature and pressure; Melting point - 103.15 ℃, boiling point - 26.1 ℃, liquid density 1.206g/cm3 (25 ℃); Generally, they are compressed into liquid and stored in steel cylinders, and their thermal properties are similar to R12. Ozone depletion potential (ODP) is 0, and global warming potential (GWP) is 1200.



3、 Product use:



1,1,1,2-tetrafluoroethane is the main substitute for CFCs sprays. At the same time, due to its low toxicity and non-flammability, it has been developed as a carrier for drug inhalers (i.e. medical aerosols). Anti-asthmatic aerosol used to treat asthma, COPD (chronic obstructive pulmonary disease) and respiratory tract infection; Nasal aerosol foam aerosol for treating allergic rhinitis; Oral and local aerosols (such as promoting neurosensitivity, enhancing tooth vitality and relieving pain), etc.




Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used gas chromatography to determine non-condensable gas in 1,1,1,2-tetrafluoroethane (HFC-134a) in Chinese Pharmacopoeia 2020, with high column efficiency, good separation and satisfactory results.
