Abstract

Solid phase microextraction is a fast, solventless alternative to conventional sample extraction techniques. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and a polymer-coated fused fiber, then are desorbed from the fiber to a chromatography column. Because analytes are concentrated on the fiber, and are rapidly delivered to the column, minimum detection limits are improved and resolution is maintained. SPME is compatible with analyte separation/detection by gas chromatography or HPLC, and provides linear results for wide concentrations of analytes.

SPME offers some important advantages:

1. Single Step Extraction - reduces sample preparation time by 70%
2. Versatility - various selectivities available, adapts to any GC or HPLC system, can be automated
3. Efficient & Economical - little/no use of solvents, quantitative method, allows more than 50 extractions per fiber on average
