Single nanogram amounts of the explosives TNT, RDX, HMX, PETN and their mixtures were detected and identified in a few seconds on the surface of human skin without any sample preparation by desorption electrospray ionization (DESI) using a spray solution of methanol-water doped with sodium chloride to form the chloride adducts with RDX, HMX, and PETN while TNT was examined as the radical anion and tandem mass spectrometry was used to confirm the identifications.
通过解吸电喷雾电离（DESI），在几秒钟内就能在人体皮肤表面检测并识别出单纳克量的炸药三硝基甲苯（TNT）、黑索金（RDX）、奥克托今（HMX）、季戊四醇四硝酸酯（PETN）及其混合物，无需任何样品制备。使用掺杂氯化钠的甲醇 - 水溶液作为喷雾溶液，使RDX、HMX和PETN形成氯化物加合物，而TNT则作为自由基阴离子进行检测，并采用串联质谱法确认识别结果。
