The non-condensable gas (NCG) in the fluoromethane refrigerant is mainly accumulated by the original air in the liquid-phase refrigerant. Excessive NCG content in the refrigerant will change the parameters of the refrigeration machinery, thereby affecting the refrigeration effect. In business dealings with foreign businessmen, we learned that foreign businessmen attach great importance to the NCG content in refrigerants.

The non-condensable gas in the gas phase is a quality index that needs to be strictly controlled for refrigerant products. At present, the commonly used methods for the determination of non-condensable gases in the refrigerant gas phase in the industry are the American Air-Conditioning Heating and Refrigeration Industry Association standard AHRI700-2017 "Refrigerant Specifications" and my country&��39;s national standard GB/T 31400-2015 "Fluoroalkane Non-condensable" The six-port valve injection specified in the Determination of Gas Chromatography (NCG), and the external standard method for quantitative gas chromatography. Taking into account the convenience and speed of glass syringe injection in the daily production process, the latest implementation of the national standard GB/T 33063-2016 "General Method for Determination of Fluoroolefin Non-Condensable Gas (NCG) for Refrigerants" on May 1, 2017 In addition to the external standard method in China, a new gas chromatographic method, which uses a glass syringe to inject samples and is quantified by the calibration area normalization method, is introduced.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. describes in detail the two methods specified in the standard, and explores and studies the methods of glass syringe injection and external standard method quantification, which is convenient for analytical operators in the field of refrigerants to analyze the gas phase of refrigerants. The mastery and application of the non-condensable gas determination method.
