Oxidised compounds in aviation fuels using Nafion fibre solid phase microextraction

摘要

Nafion solid phase microextraction fibres were prepared and applied to the analysis of polar oxygenated analytes in non-polar aviation fuel matrices. The performance of the Nafion fibres was investigated and exhibited higher extraction efficiencies for polar analytes spiked into a reference non-polar fuel, compared with a commercially available polar (Carbowax) phase fibre. Oxygen-containing compounds were also tentatively identified in thermally oxidised aviation fuels using both single column and multidimensional gas chromatography with mass spectrometry.
