Discussion on the Experiment of Configuration of Low-concentration Standard Gases α-Pinene and β-Pinene
Due to α-pinene and β-pinene is widely used as intermediates in mid to high end fragrances,pharmaceutical intermediates,and raw materials for daily chemical fragrances,therefore,this paper focuses on the configuration process of α-pinene and β-pinene standard gases.Dilution method is used in the experiment to complete the configuration of low-concentration α-pinene and β-pinene mixed gas,its content stability is analyzed using conventional gas chromatography,and abnormal phenomenon is found that the concentration of β-pinene is continuouly decreasing while the concentration of α-pinene is continuouly increasing.In addition,this paper also designes and uses various types of bottle bodies and valves for research,uses two methods of injection method and dilution method to complete the configuration of α-pinene and β-pinene mixed gasα-pinene and β-pinene,and derives and analyzes the reasons for the phenomenon in the experiment,so as to provide basic data and references.
