| 摘 要： | 利用气相色谱仪 ,在样品进样经单柱分离后通过Y形管连接至两个不同选择性检测器 (NPD/FID)的方法 ,考察气相色谱操作条件对双检测器响应比值的影响及其该法用于复杂样品测定的可行性。结果表明当实验条件保持不变时 ,NPD/FID响应比值具有较好的重现性。改变检测器操作参数和色谱条件对NPD/FID响应比值都有影响 ,但相对于某一参比物计算得到的相对NPD/FID响应比值受影响很小。样品中待测组份的浓度改变不影响NPD/FID响应比值。在有标准品比对的情况下 ,NPD/FID响应比值或相对NPD/FID响应比值可以作为定性分析的一个参数。

| Abstract: | A dual-detection Gas chromatographic method for screening out abuse drugs is described A single capillary separation column is connected to a nitrogen-phosphorus detection (NPD) and a flame ionization detection (FID) by an Y-connector The ratio responded by NPD/FID is influenced by operational conditions But the relative ratio is not influenced when carbetane is used as a reference The ratio and the relative ratio can be used to screening abuse drugs |
