Solid Phase Micro-Extraction, a Versatile and Handy Tool in Environmental Trace Organic Analysis, Gets a New Class of Coatings, Polymeric Ionic Liquids

Abstract

Abstract-Solidphase microextraction (SPME) fundamentals, characteristics and application are described. The special stress is put on characteristics of sorbents used as SPME fiber coatings. Description of commercially available fibers and the present-day trends in development of new sorbents for SPME are given. Discussion is focused on possibility of application of ionic liquids (IL) and polymeric ionic liquids (PIL) as SPME fiber coatings. An example of application of PIL coating to determine volatile fatty acids in water is given.Index Terms-Environmental trace organic analysis, chromatography, solid phase microextraction, ionic liquids, polymeric ionic liquids.
