Abstract: Silica fibers (125 μm×1 cm) were coated with 3 μm-thick Tenax-TA films and investigated for possible use in solid-phase microextraction. The performance of these fibers was evaluated by comparing them with commercially available polydimethylsiloxane/divinylbenzene (PDMS/DVB) SPME fibers. Performance was evaluated using static headspace extraction of n-alkanes at 25 ∘C. Results indicate the high performance of Tenax-TA coated fibers in terms of adsorption capacity and uptake saturation time. The PDMS/DVB fiber saturated after 25 minutes while Tenax-TA fiber saturated after 40 minutes. The uptake capacity of the Tenax-TA fibers was only half of what was retained with the 65 μm-thick PDMS/DVB fiber.
