液液萃取法和水蒸气蒸馏萃取法均需使用昂贵且有毒的有机试剂,耗时长和必需的溶剂处理。动态固相萃取能彻底消除溶剂,但需气相色谱进样器的大规模改动或增加一个解吸附模块。固相微萃取(SPME)解决了动态固相萃取的缺点并保留其优点。溶剂完全消除并且萃取时间缩短到几分钟。SPME近年来已发展成为一种快速,廉价,无需溶剂的方法。采用一个内涂聚合物的精良熔融石英纤维来提取基质中的有机物然后可以直接将其转移至气相 Both liquid-liquid extraction and steam distillation extraction require the use of expensive and toxic organic reagents, which take a long time and require solvent treatment. Dynamic SPE removes solvents completely, but requires large-scale changes to the GC samplers or the addition of a desorption module. Solid-phase microextraction (SPME) addresses the shortcomings of dynamic solid-phase extraction and preserves its advantages. The solvent is completely eliminated and the extraction time is reduced to a few minutes. In recent years, SPME has evolved into a fast, inexpensive, solvent-free method. The use of a fine polymer-coated fused silica fiber to extract the matrix of organic matter can then be transferred directly to the gas phase
