Ambient Ionization MS Analysis of Swabs Used for Explosives Detection

In DESI and DART sources, RDX is mainly detected by the attachment of an anion, although [RDX-H]- can appear on mass spectra in very low abundance (because of low gas phase methylene acidity). Characteristic adduct ions include [RDX+HCOO]-, [RDX+CH3COO]-, [RDX+CI]", or [RDX+NCg- produced in com...

Zusammenfassung:In DESI and DART sources, RDX is mainly detected by the attachment of an anion, although [RDX-H]- can appear on mass spectra in very low abundance (because of low gas phase methylene acidity). Characteristic adduct ions include [RDX+HCOO]-, [RDX+CH3COO]-, [RDX+CI]", or [RDX+NCg- produced in competition and arising from the sample environment. Without additive use, these adduct anions are formed indifferently.
