Abstract:

A new analytical method for the determination of eight explosives in ground water was independently validated. The following eight explosives were studied HMX, RDX, Tetryl, TNT, PETN, Nitroglycerin, 2,6-DNT, and 2,4-DNT. The same method had been recently developed and validated by Battelle Laboratories, Columbus Div. USAEHA Certified Reporting Limits range from 0.8 to 22 micrograms Liter, whereas Battelle values had ranged from 0.9 to 15 microgramsLiter. The method involved collection of explosives in 500 ml of groundwater onto a 600 mg Hayesep R solid sorbent cartridge, followed by elution of the cartridge with acetone. A solvent exchange to 2 ml methanolwater was performed and the solution analyzed by liquid chromatography using tandem ultraviolet photoconductivity detectors. A study of approximately thirty potential method interferants and explosive precursors was conducted. Some of these were found to be method interferants. Some recommendations for procedural modifications are made to further improve the method. Keywords Liquid chromatography Test methods Quantitative analysis Explosive precursorsdegradation products Hayesep R procedure Chromatographic analysis.
