Jet Propellant-8 (JP-8) is a military fuel associated with a large percentage of chemical exposures documented by the US Department of Defense. A fast and sensitive solid-phase microextraction-gas chromatographic-in ass spectrometric (SPME-GC-MS) method has been developed for the determination of 34 'marker compounds' found in JP-8. Linear ranges (R-2 > 0.99) were determined for each marker component and precision was measured (<16% RSD) for these components over four concentrations within each calibration range. The method was applied for the analysis of JP-8 components from soil. The use of SPME over other sample extraction techniques eliminates solvents, minimizes sample handling, and increases sensitivity. (C) 2008 Elsevier Ltd. All rights reserved.
