Desorption electrospray ionization (DESI), an ambient mass spectrometry technique, is used for trace detection of the explosives trinitrohexahydro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), 2,4,6-trinitrotoluene (TNT), Pentaerythritol tetranitrate (PETN), and their plastic compositions (Composition C-4, Semtex-H, Detasheet) directly from a wide variety of surfaces (metal, plastic, paper, polymer) without sample preparation or pretreatment. Analysis of the… 
Fabric analysis by ambient mass spectrometry for explosives and drugs.
TLDR
Desorption electrospray ionization was used to examine cotton transfer swabs used for travel security sample collection in the screening process and high throughput quantitative analysis of fabric surfaces for targeted analytes is reported.
Analysis of nitrogen-based explosives with desorption atmospheric pressure photoionization mass spectrometry.
TLDR
DAPPI could become an important method for the direct analysis of nitroaromatics from a variety of surfaces for compounds that are thermally labile, or that have very low vapor pressure, however, DESI is better suited.
Direct detection of explosives on solid surfaces by low temperature plasma desorption mass spectrometry.
TLDR
A low temperature plasma probe constructed using dielectric barrier discharge (DBD) and employed for the detection of explosives on a variety of substrates under ambient conditions allowed direct detection of trace explosives on both conductive and non-conductive substrates, thus expanding the applicability ofLow temperature plasma desorption mass spectrometry.
Direct detection of explosives on solid surfaces by mass spectrometry with an ambient ion source based on dielectric barrier discharge.
TLDR
The DBDI-MS method represents a simple and rapid way for the detection of explosives with high sensitivity and specificity, which is especially useful when they are present in trace amounts on ordinary environmental surfaces.
Identification of explosives and explosive formulations using laser electrospray mass spectrometry.
Mass analysis is demonstrated for the detection of sub-microgram quantities of explosive samples on a metallic surface at atmospheric pressure using laser electrospray mass spectrometry (LEMS). A
Sensitive ionization of non-volatile analytes using protein solutions as spray liquid in desorption electrospray ionization mass spectrometry.
TLDR
The proposed DESI method is a universal strategy for rapid and sensitive detection of trace amounts of strongly bound and/or non-volatile analytes, including explosives, peptides, and proteins.
Desorption electrospray ionization mass spectrometric analysis of organophosphorus chemical warfare agents using ion mobility and tandem mass spectrometry.
TLDR
A rapid screening approach, based on the developed methodology, was applied to several typical forensic media, including Dacron sampling swabs spiked with 5 microg of CWA, which readily identified the spiked CWA within one minute on the basis of the acquired ion mobility and mass spectrometric data.
Quantitative analysis of small molecules by desorption electrospray ionization mass spectrometry from polytetrafluoroethylene surfaces.
TLDR
Day-to-day measurements suggest that DESI-MS can be successfully employed for routine quantitative analysis, and studies that utilize a particularly suitable surface, porous polytetrafluoroethylene (porous PTFE), which shows less cross contamination between samples and improved sensitivity and signal stability compared to other surfaces.
Detecting reaction intermediates in liquids on the millisecond time scale using desorption electrospray ionization.
TLDR
It is demonstrated for the first time that DESI can intercept reactive intermediates in solution using mass spectrometry.
