摘要
气相色谱-氮化学发光检测法(GC-NCD)由于其对样品中氮化物等物质的量响应的特点,逐步成为使用最为广泛的测定石油炼制产物中氮化物形态的分析手段之一。GC-NCD方法对氮化物的定性主要是标样定性或者分离富集后色谱-质谱联用(GC-MS)对照定性,外标法定量。对GC-NCD法在石油炼制过程中的实际应用工作进行了梳理,将其适合分析的气体、汽油、柴油以及含氮添加剂等主要应用进行了总结。
Gas chromatography-nitrogen chemiluminescence detector(GC-NCD)has gradually become one of the most widely used analytical method for the determination of nitrogen species in petroleum refining products due to its equimolar response to nitrogen compounds in samples.The qualitative analysis of GC-NCD mainly refers to the qualitative determination of standard sample or GC-MS after enrichment and extraction,and external standard method is generally used for quantitative analysis.In this paper,the practical application of GC-NCD in petroleum refining process was summarized,and some main applications in the analysis of gas,gasoline,diesel fuel and some additives were presented.
