ActiveFluorinated alkane—Determination of non condensable gas(NCG)—Gas chromatography
氟代烷烃 不凝性气体(NCG)的测定 气相色谱法
Application Summary AI generated
This standard specifies a gas chromatography method for determining the content of non-condensable gases (NCG), such as air or nitrogen, in fluorinated alkanes. It is applied in the chemical industry for quality control of refrigerants, blowing agents, and cleaning solvents, ensuring that NCG levels remain within specified limits to maintain product performance and system efficiency. The method is particularly relevant for manufacturers and testing laboratories verifying the purity of fluorinated hydrocarbons used in refrigeration and air-conditioning systems.
