Using Single Drop Microextraction for Headspace Analysis with Gas Chromatography
Riccio, Daniel; Wood, Derrick C.; Miller, James M.
Journal of Chemical Education, v85 n7 p965-968 Jul 2008
Headspace (HS) gas chromatography (GC) is commonly used to analyze samples that contain non-volatiles. In 1996, a new sampling technique called single drop microextraction, SDME, was introduced, and in 2001 it was applied to HS analysis. It is a simple technique that uses equipment normally found in the undergraduate laboratory, making it ideal for instructional use, especially to illustrate HS analysis or as an alternative to solid-phase microextraction (SPME) to which it is very similar. The basic principles and practice of HS-GC using SDME are described, including a complete review of the literature. Some possible experiments are suggested using water and N-methylpyrrolidone (NMP) as solvents. (Contains 2 figures and 1 table.)
