TY - JOUR PY - 2015// TI - Novel method for the detection of nitroglycerin in smokeless powders JO - Science and justice A1 - Roberts, Marcel A1 - Petraco, Nicholas A1 - Gittings, Michael SP - 467 EP - 471 VL - 55 IS - 6 N2 - Nitroglycerin is an active component in many explosive substances. Notably, it is found as an active ingredient in double-base smokeless powders, differentiating them from single-base powders, whose main active ingredient is nitrocellulose. It is proposed that the detection of nitroglycerin within various types of ammunition will allow for the differentiation between single and double-base smokeless powders, thus allowing for a method of distinguishing ammunition or bulk powder samples that may be found during the course of a criminal investigation. Presumptive tests are an effective tool in field-testing for forensic science. These tests are used primarily as rapid, sensitive means of elucidating the chemical characteristics of an unknown sample in-situ. In this paper, the authors present a novel method for the detection of nitroglycerin in smokeless powders with the use of a presumptive color test reagent, dimethylaminocinnamaldehyde (p-dmac). Twenty-five smokeless powders were tested using this reagent to evaluate the color change that would occur in the presence of nitroglycerin. All presumptive results were confirmed via gas chromatography-mass spectrometry.
