ActiveCoal tar—Determination of component content—Gas chromatography-mass spectrometry and thermogravimetry
煤焦油 组分含量的测定 气相色谱-质谱联用和热重分析法
Application Summary AI generated
This standard specifies a method for determining the component content of coal tar using gas chromatography-mass spectrometry (GC-MS) and thermogravimetry (TG). It is applied in the chemical and coking industries for quality control and process optimization of coal tar, particularly in the production of coal-based chemicals and fuels. The method is used in laboratory testing to analyze complex mixtures of aromatic hydrocarbons and other volatile compounds in coal tar samples.
