侦测燃料标记物之分析方法;ANALYTICAL METHOD FOR DETECTING FUEL MARKERS

摘要

以下列两个通道侦测燃料中第一标记物化合物及第二标记物化合物之气相色层分析方法：(i)涂有聚矽氧烷之第一毛细管柱以及涂有聚乙二醇之第二毛细管柱；以及(ii)涂有聚甲基苯基矽氧烷之第三毛细管柱以及去活化之第四毛细管柱。该等步骤系：(a)将第一样品引入第一管柱中以产生第一出流；(b)仅将该第一出流之一部份引入第二管柱中以产生第二出流；(c)令该第二出流穿行通过质谱仪；(d)将第二样品引入第三管柱中以产生第三出流；(e)仅将该第三出流之一部份引入第四管柱中以产生第四出流；(f)令该第四出流穿行通过质谱仪。; and (ii) a third capillary column coated with polymethylphenylsiloxane and a fourth deactivated capillary column. The steps are: (a) introducing a first sample into the first column to produce a first effluent; (b) introducing only a portion of the first effluent into the second column to produce a second effluent; (c) allowing the second effluent to pass through a mass spectrometer; (d) introducing a second sample into the third column to produce a third effluent; (e) introducing only a portion of the third effluent into the fourth column to produce a fourth effluent; (f) allowing the fourth effluent to pass through a mass spectrometer.
