✦ Synopsis

In this paper, some theoretical and practical aspects of solid-phase microextraction coated fibers will be discussed in detail. The surfaces of a series of prepared fibers have been characterized by chromatographic methods. The Ž . following fibers were tested: ethoxy-polydimethylsiloxane coated fibers PDES , polyurethaneacrylate coated fiber, fused silica fiber, and fused silica fiber after etching with hydrofluoric acid. Sorption properties for each fiber were examined using BTEX standards in methanol. The time needed for the analyte to reach equilibrium between the sample and the fiber was determinated. The extraction time profiles for individual fiber coatings were established by plotting the extracted mass versus the extraction time. The efficiencies of extraction for the tested fibers Ž . and for polydimethylsiloxane PDMS used as a reference fiber were compared.

Ž . The distribution constants of the polymer coatingraqueous phase K for determined BTEX were calculated and compared with conventional K data for ow octanolrwater.
