Application Of Gas Chromatography In Organic Trace Analysis

The paper consists of four chapters. In chapter 1,the recent progress of GC in organic trace analysis has been reviewed, including pretreatments of the samples, application field and application examples. Relative references were 63. In chapter 2, the gas chromatographic separation condition of several natural and synthetic estrogens was optimized. SPE as a pretreatment method, the estrogens in river water were determined. In chapter 3, an enrichment method——micro-distillation was investigated, with which low molecular fatty alcohols in aqueous samples was determined by GC. In chapter 4, the residual organic solvents in Dexamethasone Sodium Phosphate was determined with packed column GC.
