| Zusammenfassung: | The invention aims at overcoming the defects of the existing sample detection technology, and particularly relates to a method for determining geosmin and 2-methylisoborneol in sediments, which comprises the following steps of sampling, headspace solid phase micro-extraction and GC-MS analysis. According to the method, the extraction effects of different types of extraction heads are compared, theextraction conditions such as the extraction time, the extraction temperature and the like are optimized, the headspace solid phase micro-extraction/gas chromatography/mass spectrometry method is established to simultaneously determine the geosmin and the 2-methylisoborneol in the sediment, and the method has characteristics of sensitivity, rapidness, environmental protection and the like, can accurately quantify the odor substances in the sediment, and can meet the detection requirements of the actual sample.
本发目的在于针对现有样品检测技术的不足，具体涉及一种沉积物中土臭素和2-甲基异莰醇的测定方法，包括如下步骤：取样、顶空固相微萃取、GC-MS分析；本发明通过对比了不同类型萃取头的萃取效果，优化了萃取时间和温度等萃取条 |
