热离子化检测器(Thermionic detector,简称TID)作为气相色谱选择性检测器已有二十多年的历史。它对含氮、磷和卤素等有机化合物的检测限可达1×10~(-3)gX/sec,对磷的选择性高达1×10~2gP/gC。如此高的灵敏度和选择性已引起了色谱界对TID的普遍重视,尤其在分析痕量氮磷化合物或氮磷化合物与样品中其他组分分离不太好的情况下,使用TID有其独到之处。目前,国内外生产的大多数气相色谱仪都可装配热离子化检测器,其使用范围已涉及到医学、医药、临 Thermionic detectors (TIDs) have been the gas chromatographic selective detectors for more than two decades. Its detection limit of organic compounds containing nitrogen, phosphorus and halogen up to 1 × 10 -3 gX / sec, the selectivity of phosphorus up to 1 × 10 ~ 2gP / gC. Such high sensitivity and selectivity have caused widespread attention to the TID in the chromatographic community, especially in the analysis of trace nitrogen and phosphorus compounds or nitrogen and phosphorus compounds and other components of the sample separation is not very good case, the use of TID has its own unique Department. At present, most domestic and foreign production of gas chromatograph can be assembled thermal ionization detector, the scope of its use has been related to medicine, medicine, Pro
