A fast liquid chromatography tandem mass spectrometric analysis of PETN (pentaerythritol tetranitrate), RDX (3,5-trinitro-1,3,5-triazacyclohexane) and HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) in soil, utilizing a simple ultrasonic-assisted extraction with minimum solvent

Özet

© The Japan Society for Analytical Chemistry.Direct analyses of explosives in soil using liquid chromatography tandem mass spectrometry (LC-MS/MS) methods are very limited in the literature and require complex procedures or relatively high amount of solvent. A simple and rapid method was developed for the determination of pentaerythritol tetranitrate (PETN), 3,5-trinitro-1,3,5-triazacyclohexane (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), which are among the explosives used in terrorist attacks. A one-step extraction method for 1.00 g soil with 2.00 mL acetonitrile, and a 8-min LC-MS/MS method was developed. The detection limits for PETN, RDX and HMX were 5.2, 8.5 and 3.4 ng/g and quantitation limits were 10.0, 24.5, 6.0 ng/g. The intermediate precisions and Horwitz Ratio's were between 4.10-13.26% and 0.24-0.98, in order. This method was applied to a model post-blast debris collected from an artificial explosion and real samples collected after a terrorist attack in Istanbul. The method is easy and fast and requires less solvent use than other methods. 2016.
