Characterization of Smokeless Powders using Multiplexed Collision-Induced Dissociation Mass Spectrometry and Chemometric Procedures

Smokeless powders are low explosives that constitute the propellant in ammunition cartridges [1,2]. Powders consist of the explosive material, which is typically nitrocellulose (single base) or nitrocellulose and nitroglycerin (double base), along with a series of additives that impart specific properties [2]. Among these additives are stabilizers such as diphenylamine, methyl centralite, and ethyl centralite, plasticizers such as dibutyl phthalate, and deterrents such as dinitrotoluene [2]. In terms of forensic analysis, smokeless powders may be analyzed in the form of the unburned powder or as a residue after a firearm has been discharged [3 –6].
