| Abstract: | Desorption electrospray ionization mass spectrometry(DESI-MS) was applied to the rapid detection of trace amounts of RDX on surfaces of various material,including rock,paper,cloth,leather,Teflon,rubber etc.,without sample preparation and pretreatment.Under the optimized operation parameters,the quasi-molecular ion peak of RDX at m/z 223 was obtained with a mixture of methanol and acetic acid(98+2) as the electrospray solvent,and the characteristic peak of the fragment of RDX at m/z 177 was confirmed by MS/M... |
