一、前言气相色谱-质谱联用(GC/MS)因兼有优良的分离能力,较高的灵敏度和丰富的结构鉴别信息而被公认为分析挥发性复杂有机混合物的最有效的方法。我们从1975至1980年间用有机溶剂萃取富集,用填充柱的GC/MS分离分析松花江水中有机污染物,历时六年累计检出化合物只有64种,1981年采用大孔网状树脂吸附富集以加大富集倍数(采水样25升),采用玻璃毛细管气相色谱柱(GCGC或GC~2)以替换填充柱,增强了
I. Introduction GC / MS is recognized as the most effective method for the analysis of volatile complex organic compounds because of its excellent separation ability, high sensitivity and abundant structure identification information. We used organic solvent extraction and enrichment from 1975 to 1980. The organic pollutants in the Songhua River water were separated and analyzed by packed column GC / MS. Only 64 compounds were detected in six years. In 1981, macroporous reticulated resin was used for adsorption Enrichment to increase the enrichment multiple (25 liters of water sample), the use of glass capillary GC (GCGC or GC ~ 2) to replace the packed column, enhanced
