摘　　要：气相色谱-原子发射光谱(gas chromatography with microwave-induced plasma atomic emission detection, GCAED)是一种特色鲜明的分析仪器,兼具色谱的分离能力和高灵敏度的元素检测能力,广泛应用于多个领域,可作为油品中含氮化合物强大的分析仪器。本文从仪器组成、检测原理和特点三方面综述了GC-AED的研究进展,重点阐述了等摩尔响应及元素比例式的推断应用。对比了氮的两个检测通道(174nm和388nm)的研究现状,发现在388nm处具有等摩尔响应特性和更高的选择性;目前利用GC-AED对含氮化合物检测主要是在388nm处,评述了在388nm对油品中含氮化合物检测的影响因素,并整理出了一套适用的气体条件实现了化合物无关校正,可用于定量分析。并对GC-AED分析技术的应用前景作了展望,结合其他分析仪器有望扩大其应用领域。Gas chromatography with microwave-induced plasma atomic emission detection(GC-AED)is a distinctive analytical instrument,which has both chromatographic separation ability and high sensitivity for element detection.It is widely used in many fields and can be used as a powerful analytical instrument for nitrogen compounds in oil products.The research progress of GC-AED is reviewed from three aspects:instrument composition,detection principle and characteristics,with emphasis on the application of equal molar response and element proportional inference.The research status of two nitrogen detection channels(174nm and 388nm)is compared,and it is found that there is equal molar response and higher selectivity at 388nm;at present,the detection of nitrogen compounds by GC-AED is mainly at 388nm,the factors affecting the detection of nitrogen compounds in oil products by 388nm are reviewed,and a set of suitable gas conditions are sorted out to achieve compound independent correction,which can be used for quantitative analysis.The application prospect of GC-AED analytical technology is prospected,and its application field is expected to be expanded with other analytical instruments.
