摘要
选用Ｃ１８固相萃取柱，从原油中同时分离出了烷基苯酚和中性含氮化合物，并在适合的ＧＣＭＳ条件下，首次实现了一次进样同时检测出这两类化合物。这一方法具有快速、高效、经济的特点，适合于油藏地球化学研究中批量样品分析的需要。
A new method of rapid separation for phenols and neutral nitrogen compounds in crude oils is established by using C_18 solid phase extraction(SPE) column. GCMS conditions are determined under which analysis and identification of alkylphenols, alkyl carbazoles and benzocarbazoles in neutral nitrogen fraction can be done at the same time by one injection This method is characterized by rapid, efficient and economic analysis, and is suitable for analysis of many samples in reservior geochemistry study
