采用解吸电喷雾电离（DESI）技术，利用掺杂氯化钠的甲醇-水喷雾溶液，与RDX、HMX、PETN形成氯化物加合物，在人体皮肤表面几秒钟内检测并鉴定出单纳克量的炸药TNT、RDX、HMX、PETN及其混合物，而TNT则作为自由基阴离子进行检测，并采用串联质谱法进行鉴定。
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.
