摘要

固相微萃取是集進樣、萃取和濃縮功能於一體的新萃取技術，主要是基於萃取塗覆層與樣品之間的吸附/吸收-脫附平衡的原理，為一種具有方便、快捷、不需使用有機溶劑、靈敏和價廉等優點之樣品前處理技術。本文介紹了固相微萃取技術的裝置、原理、操作方法。並且說明其萃取條件選擇，包括不同塗覆層的萃取纖維、萃取時間、萃取溫度、攪拌方法、萃取方式等因素對固相微萃取的萃取效率的影響，同時對SPME在環境分析、藥物分析、食品分析和天然香料分析等領域中的應用近況，作一回顧介紹。

Solid-phase microextraction (SPME) is a technique with functions of sampling, extracting and concentrating based on adsorption/absorption-desorption equilibrium between coating and sample. It is a simple , fast, highly sensitive ,economic and solvent-free sample preparation technology. This paper describes the structure, principle including equilibrium theory as well as equilibrium theory and sampling method of solid-phase microextraction. Especially the optimum extraction parameters include fiber , extracting time and extracting temperature were introduced. Its applications in environmental analysis, drug analysis , food analysis and flavor analysis were reviewed.
