JHTD-DART-MS (a) negative mode extracted ion chronograms (XICs) for a mixture of 100 ng each of DNT, PETN, and PC and (b) positive mode XICs for a mixture of 100 ng each of HMTD and PC at a heating rate and maximum temperature of 125 °C s−1 and 335 °C. (c) Traditional DART-MS (at 350 °C) directly off of the nichrome wire, followed by JHTD-DART-MS burst (355 °Cs−1 and 629 °C) of a 100 ng mixture of PETN and PPC. Arrows indicate initiation of current burst for JHTD. (i)–(iii) Demonstrative extracted mass spectra from respective locations denoted by blue boxes in the chronograms (a)–(c).
