Nanosized Polymeric Fibres for Solid-phase Microextraction Sorbents
Original language description
Solid phase microextraction (SPME) has been established as a convenient method of sample preparation in organic analytical chemistry since its introduction by Pawliszyn in the nineties of the 20th century. Recently, first attempts are reported on the preparation of SPME sorbents by electrospun nanofibres, in contrast to routinely applied sol-gel techniques. The intention of using electrospun fibres geometry is to enhance the sorbent sensitivity and capacity. In this work, polyetherimide (PEI) electrospun nanofibres were prepared from PEI 15 % solution in DMF/THF 80:20 using a needle electrospinner and SPME steel core as electrode under 10 kV. Adhesion between steel core and polymeric coating was optimized to obtain thermally stable PEI/PDMS SPME fibre assembly. Final laboratory-made SPME fibres were characterized by SEM and TGA and their analytical performance (in determination of hexachlorocyclohexanes - HCH by headspace-SPME GC/MS) was compared with commercially available SPME fibres.
