Quantitative Analysis of Trace C_1-C_5 Hydrocarbons by Absorption/Thermal Desorption Gas Chromatography

    摘要
  • 摘要: 本文以活性炭、TDX-01、TenaxGC、PorapakQ和GDX-104为吸附剂,不经冷凝,在常温下吸附富集痕量C1～C5烃并直接引入毛细管柱。同时探讨了吸附剂的最佳热脱附温度、饱和吸附量、吸附富集回收率、热脱附直接进样的线性规律及方法的相对偏差。

     

    Abstract: The trace C1～C5 hydrocargbons can be enriched by adsorbents-activatal carbon, TDX-01,Tenax GC, Polapak Q or GDX-104 in ambient temperature and be introduced directly to a capillary column without using a cryogenic trap.The optimum temperature of thermal desorption, the saturated adsorptive capcity and recovery of these adsorbents were investigated.
