Paper Abstract

Characterization of hexamethelene triperoxide diamine (HMTD), tetramethylene diperoxide dicarbamide (TMDD) and tetramethylene diperoxide acetamide (TMDA) has been carried out using Direct Analysis in Real Time/Time of Flight Mass Spectrometry (DART-TOF/MS). The study also centered in the detection of their precursors such as hexamine and formaldehyde. Analysis of the compounds by GC-MS was also conducted. HMTD shows a clear peak at 209 m/z that allowed its detection in standard solutions and lab made standards. TATP samples with deuterium enrichment are being analyzed to compare results that could differentiate from HMTD and similar substances. All samples were characterized by Raman and FT-IR to confirm the DART results. Some of the vibrations observed were in the ν(O-O), ν(N-C), ν(N-H), ν(C-O), δ(CH3-C) and δ(C-O). Development methodology for trace detection was compared with GC/MS and HPLC-MS results previously presented for HMTD and TATP.
