气相色谱/质谱/数据处理系统,近年来已成为强有力的分析手段,这种手段兼有色谱分离和质谱的鉴定技术。自1975年我们从事色谱/质谱/数据处理系统工作以来,使用VARIN AEROGRAPH 2740色谱仪/MAT 311质谱计/SS-100MS 数据处理系统,在石油产品领域内,例如汽油中的单体化合物和柴油中的碱性氮化物的鉴定。讨论了某些技术问题,包括富集因子和使用不同分离器样品的收率、选择色谱柱和它们的评价原则,尤其是使用弹性熔融石英毛细管柱的优点、石墨密封材料和数据处理系统操作参数的选择等。
Gas chromatography / mass spectrometry / data processing systems have become powerful analytical tools in recent years, both as a chromatographic separation and mass spectrometry technique. Since our work in Chromatography / Mass Spectrometry / Data Processing Systems in 1975, the VARIN AEROGRAPH 2740 Chromatograph / MAT 311 Mass Spectrometer / SS-100MS Data Processing System has been used in the petroleum product sector, for example in monomer compounds in gasoline and diesel The identification of basic nitrides. Some technical issues are discussed, including enrichment factors and yield using different separator samples, column selection and their evaluation principles, especially the advantages of using flexible fused silica capillary columns, graphite seal materials and data processing system operating parameters Choice and so on.
