This critical review presents information on known and innovative approaches to the manufacture of fibre coatings used in solid-phase microextraction (SPME). The properties, advantages and drawbacks of the different types of commercially available SPME fibre coatings are discussed in detail, as are those of novel types of coatings and the methodologies of their preparation. The applications of fibre coatings in the solid-phase microextraction of a broad spectrum of analytes are analysed, with particular emphasis on the sampling of polar analytes from polar matrices (174 references).

Current trends in solid-phase microextraction (SPME) fibre coatings

Recent developments in solid-phase microextraction coatings and related techniques.

Recent developments and future trends in solid phase microextraction techniques towards green analytical chemistry.

Analytical chemists are faced with the daunting challenges of accurately monitoring the state of the environment and the processes taking place in it and of determining an enormous range of analytes often present in trace and ultratrace amounts in sample matrixes with complex or variable compositions. Further challenges are presented by the need to introduce new methodologies into current analytical practice and equipment to comply with the principles of sustainable development and green chemistry. Highest among these principles is the elimination or at least the substantial reduction of the quantities of reagents consumed (especially organic solvents and toxic compounds), solid and liquid wastes produced, and vapors and gases emitted. In analytical chemistry these principles are implemented above all by the utilization of ever more sensitive and automated instruments and of monitoring equipment which allows many analytes to be determined in a single analytical run, by the wide application of direct analytical techniques, operating in situ, and by the introduction of additional isolation and/or preconcentration steps prior to the final determination.
