Nanosized polymeric fibres for solid-phase microextraction sorbents
Original language description
Solid phase microextraction (SPME) has been established as a modern, simple, sensitive, rapid and solvent free technique for sample preparation in organic analytical chemistry. Since SPME was first introduced by Pawliszyn in the early 1990s, several modifications of sorbent geometry were developed. The main goal of using electrospun fibres geometry is to enhance the sorbent sensitivity and capacity. In the present work, electrospun polyetherimide (PEI) nanofibres were prepared from 12.5 % solution (80/20 – DMF/THF) fixed on a steel wire solid phase microextraction (SPME) assembly. Analytical performance of prepared fibres was compared with common commercial available SPME fibres (100 µm polydimethylsiloxane (PDMS), 65 µm polydimethylsiloxane/divinylbenzene (PDMS/DVB) and 85 µm polyacrylate (PA)) in the headspace SPME (HS-SPME) mode of gas chromatograph coupled with mass spectrometer (GC/MS/MS). The chlorophenols were chosen as model water pollutants. To solve instability, tailing peaks, detectability and adsorption problems, chlorophenols were acetylated before GC step of the analysis. Lab-made PEI nanofibres assemblies appeared to have sensitivity comparable to commercial SPME fibres.
