Solid Phase Microextraction (SPME) and Its Application in Food Analysis

Solid phase microextraction (SPME) is a new extraction technique which is based on the solid phase extraction(SPE). This system consists of sampling, extraction and concentration in one unit and has the advantage of simple operation, rapid analysis, low cost, safety, good resolutio, high sensitivity and being free of organic solvents. The underlying principle and operation were summarized in this paper. The optimum parameters and conditions, as well as its application in food analysis were reviewed. Its future development was also discussed in this paper.
