Koeberg, M. van der Heijden, A.E.D.M. van Driel, C.A. Blaga, C. Bruinsma, J. van Asten, A.C. Publication year 2016 Abstract Studying links between triacetone triperoxide (TATP) samples from crime scenes and suspects can assist in criminal investigations. Isotope ratio mass spectrometry (IRMS) and gas chromatography (GC)-IRMS were used to measure the isotopic compositions of TATP and its precursors acetone and hydrogen peroxide. In total, 31 TATP samples were synthesized with different raw material combinations and reaction conditions. For carbon, a good differentiation and a linear relationship were observed for acetone–TATP combinations. The extent of negative (d13C) fractionation depended on the reaction yield. Limited enrichment was observed for the hydrogen isotope (d2H) values of the TATP samples probably due to a constant exchange of hydrogen atoms in aqueous solution. For oxygen (d18O), the small isotopic range and excess of water in hydrogen peroxide resulted in poor differentiation. GC-IRMS and IRMS data were comparable except for one TATP sample prepared with high acid concentration demonstrating the potential of compound-specific isotope analysis. Carbon IRMS has practical use in forensic TATP investigations. © 2016 American Academy of Forensic Sciences Subject Observation, Weapon & Protection SystemsEM - Energetic MaterialsTS - Technical SciencesExplosivesExplosivesForensic scienceGas chromatography isotope ratio mass spectrometryIsotope ratio mass spectrometryPrecursorsTriacetone triperoxide To reference this document use: http://resolver.tudelft.nl/uuid:e0fc1fbf-e9ae-4a5a-8635-3c5043560202 DOI https://doi.org/10.1111/1556-4029.13135 TNO identifier 572352 Publisher Wiley ISSN 0022-1198 Source Journal of Forensic Sciences, 61 (5), 1198-1207 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
