摘　　要：目标物样品的制备在复杂基体分离和测定中是一个极为重要的步骤。近年来,样品制备的发展方向是小型化、自动化和高效化,最近10年出现了填充吸着剂微萃取(Microextraction by packed sorbent,MEPS),这是一种简单的快速在线进样技术,只需要少量样品和少量洗脱溶剂。简单介绍了MEPS技术,包括其构型、应用场合以及所使用的吸着剂。Sample preparation is an important stage in separation and determination of components of interest from complex matrices. Recent trends in sample preparation are miniaturization,automation, highthroughput. In the past decade,microextraction by packed sorbent （MEPS） was introduced as a simple, fast, on-line sample-preparation technique, M EPS only requires less sam- ple and less eluent solvent. This paper briefly introduces MEPS technique, including fields of application, common formats and sorbents is introduced.
