“…The factor that had the biggest effect on the separation was the type and concentration of organic additive in the mobile phase. As observed in previous studies of HPLC separations with nitroaromatic compounds using C18 stationary phases, methanol was the mobile-phase modifier that gave the best overall separations . Acetonitrile is known to have a higher elution strength than methanol.…”

“…These disadvantages have led to the search for alternative liquid chromatographic techniques to the traditional isocratic HPLC separation of explosives. Emmrich and co-workers investigated the use of mobile-phase gradients using a single C18 column. Using a C8 stationary phase under isocratic conditions and photodiode array detection, Bouvier and Oehrle 5 were able to identify all of the method 8330 components in under 25 min, but were unable to achieve baseline resolution.…”

The identification of explosives and their degradation products is important in forensic and environmental applications. Complete separation of these structurally similar compounds using reversed-phase liquid chromatography has proven to be a challenge. Here we present a demonstration of the use of capillary electrochromatography on the separation of a series of 14 nitroaromatic and nitramine explosive compounds. A separation with baseline resolution is achieved for all of the compounds in under 7 min, featuring efficiencies of over 500 000 theoretical plates/m. Using more aggressive running conditions, 13 of the 14 compounds are separated in under 2 min.

“…Due to demilitarization and cleanup of areas previously used for munitions storage and processing, there is a need for a fast, reliable, inexpensive, and sensitive sensor for explosive detection in soil and groundwater. Various analytical methods, such as HPLC, GC, MS, and X-ray imaging, and sensor devices, have been reported in the literature for the detection of explosives. − The figures of merit of a majority of these reports have been summarized in our recent paper reported on the analysis of explosives using a proton nuclear magnetic resonance ( 1 H NMR) spectroscopic method which offers high resolution and selectivity but the limit of detection (for all the tested explosives) is on the order of 1−10 μg/mL.…”

“…The method consisted of SPE with Amberlite XAD 2/4/8, elution with dichloromethane and RP-HPLC-UVD with a photodiode array at their optimum wavelength; LOD was ca 50 ng/L with 85 105% recoveries, depending on the compound 445 . Good separations were achieved with methanol water gradient and a methanol water gradient containing 2% of THF, with different elution orders for nitrated benzenes, nitrated toluenes and nitrated toluidines 459 .…”
