英文摘要 | The mechanism of Solid- phase microextraction is based on an equilibrium of analyte concentration between the sample and that in the soild-phase fiber coating. The analytes are directly determined by thermal desorption into a gas chromatograph. This study evaluates soild-phase microextraction (SPME) coupled with gas chromatography to determine trace levels of 95 unleaded petrol accerlrant. Headspace extraction was used in this study. The optimum conditions for extraction are systevatically studied including extraction time、extraction temperature and adding salt. |
