摘要
基于中空纤维的液相微萃取集采样、萃取、浓缩于一体,具有成本低,溶剂用量少,易与高效液相色谱、气相色谱、毛细管电泳联用等特点。该技术不仅可实现较高的回收率和富集效率,而且具有突出的样品净化功能,是一种环境友好的样品前处理新技术。该文对基于中空纤维的液相微萃取的装置、操作模式、基本原理及近年来应用研究的进展进行了综述。
The liquid-phase microextraction (LPME), based on disposable hollow fiber, has been developed to be a new environmentally benign sample preparation technique which incorporate sampling, extraction and concentration into a single step. The novel technique can be easily manipulated in combination with high performance liquid chromatography, gas chromatography and capillary electrophoresis, and can provide excellent sample clean-up effect and high degree of extraction recovery and enrichment. It is proved to be simple, low-cost and virtually solvent-free. The extraction set-up, extraction mode, basic principles and recent applica- tions of the hollow fiber-based liquid-phase microextraction are reviewed.
