本文讨论了应用102G 型气相层析仪——氮磷检测器(GC—NPD)联接毛细管柱后的性能及用于分析实际样品的情况。在氮磷检测器上联接毛细管柱,既保证了该检测器的高选择性和灵敏度,又使实际环境水样中的含氮有机物的分离能力得到明显提高。在分析第二松花江吉林江段水样中及吉化公司主要污水排放口水样中含氮有机化合物时,定性检出20种含氮有机物,并对其中18种有机物进行了定量。采用高分子微球 GDX
This article discusses the performance of a 102G GC-NPD coupled capillary column and the analysis of actual samples. The combination of capillary column on the nitrogen and phosphorus detector not only ensures the high selectivity and sensitivity of the detector, but also significantly improves the separation ability of the nitrogen-containing organic matter in the actual environmental water sample. Twenty kinds of nitrogenous organic compounds were qualitatively identified and 18 of them were quantified when analyzing the nitrogenous compounds in the water samples from the second section of the Songhua River in Jilin Province and the water samples from the main effluent of Jilin Chemical Company.
