The trace polar species present in diesel were investigated by combining selective ionization with high resolution mass spectrometry. To eliminate matrix effects, the polar fraction was extracted using methanol and direct infusion with electrospray ionization and mass analysis were performed. The advantages and limitations of time-of-flight mass spectrometry and Fourier transform ion cyclotron resonance mass spectrometry for diesel analysis were discussed.Complementary information was obtained by considering both positive and negative ion mass spectra in terms of compounds that form part of the inherent fuel composition and compounds that represent fuel additives. Additionally, diluted fuels were separated by gas chromatography prior to atmospheric pressure chemical ionization and mass analysis. Results showed that a large portion of unsaturated polycyclic hydrocarbons were not detected during direct infusion experiments, indicating that these species were not extracted efficiently with methanol and/or ionized efficiently with electrospray.

“…Conventional GC systems offer high peak capacities and generally provide suffi cient resolution of compounds. However when analysing highly complex samples with a variety of components such as decomposition odour, the peak capacities offered by such systems are not able to suffi ciently resolve all components (Dalluge et al 2003 ;Dekeirsschieter et al 2012 ). Comprehensive two dimensional gas chromatography (GC × GC) is an emerging technique that provides the additional peak capacity required for the analysis of complex samples, however its wide range of potential applications are not well represented in the literature (Dalluge et al 2003 ).…”

a b s t r a c tToxaphene, which is a broad spectrum chlorinated pesticide, is a complex mixture of several hundred congeners, mainly polychlorinated bornanes. Quantifying toxaphene in environmental samples is difficult because of its complexity, and because each congener has a different response factor. Toxaphene chromatograms acquired using one-dimensional gas chromatography (1DGC) show that this technique cannot be used to separate all of the toxaphene congeners. We developed and validated a sensitive and quantitative method for determining three indicator toxaphene congeners in soil using an isotope dilution/comprehensive two-dimensional gas chromatography-tandem mass spectrometry (GC Â GC-MS). The samples were extracted using accelerated solvent extraction, and then the extracts were purified using silica gel columns. 13 C 10 -labeled Parlar 26 and 50 were used as internal standards and 13 C 10 -labeled Parlar 62 was used as an injection standard. The sample extraction and purification treatments and the GC Â GC-MS parameters were optimized. Subsequently the samples were determined by GC Â GC-MS. The limits of detection for Parlar 26, 50, and 62 were 0.6 pg/g, 0.4 pg/g, and 1.0 pg/g (S/N ¼3), respectively, and the calibration curves had good linear correlations between 50 and 1000 μg/L (r 2 40.99). Comprehensive two-dimensional GC gave substantial improvements over onedimensional GC in the toxaphene analysis. We analyzed soil samples containing trace quantities of toxaphene to demonstrate that the developed method could be used to analyze toxaphene in environmental samples.
