Thin film microextraction (TFME) approach recently aroused in the scientific literature as one of the alternative to the
solid phase microextraction (SPME) based on the fiber geometry. Generally, in theory, not different from SPME, TFME
possesses several important advantages. Since the amount of analytes extracted in SPME is proportional to the volume of the
extraction phase, the sensitivity of a method can be improved by increasing the volume of the extraction phase. In general, this
extraction approach exhibits much higher extraction rates than SPME fiber due to the higher surface area to extraction phase
volume of the thin film. In this technique, scientists used a thin sheet of PDMS membrane attached to a deactivated stainless
steel rod like a flag.
In current research, we investigated a class of hybrid materials of zeolite and polydimethylsiloxane. Such hybrid materials
have been previously reported for several tasks, in particular, selective filtration due to size exclusion mechanism. However,
these composites were not thoroughly studied for the chemicals sorption, retention and controlled release purposes. They not
only possess longer retention of targeted analytes due to size-fitting on the zeolite pores but also can be used for enhanced
preconcentration and selectivity over conventional PDMS as a solid extraction phase. More detailed results will be presented
at the conference.
