The Analyst, 2010
Mass spectrometry allows rapid chemical analysis of untreated samples in the ambient environment. This is a result of recent rapid progress in ambient ionization techniques. The most widely studied of these new methods, desorption electrospray ionization (DESI), uses fast-moving solvent droplets to extract analytes from surfaces and propel the ...

Ambient molecular imaging by desorption electrospray ionization mass spectrometry
Nature Protocols, 2008Desorption electrospray ionization (DESI) allows the direct analysis of ordinary objects or pre-processed samples under ambient conditions. Among other applications, DESI is used to identify and record spatial distributions of lipids and drug molecules in biological tissue sections.

Analytical Chemistry, 2009
The general ion chemistry of the explosive molecule cyclotrimethylenetrinitramine (RDX) was studied with an atmospheric pressure ionization mass spectrometer (API-MS) fitted with a desorption electrospray ionization (DESI) source. Explosive molecule chemistry within trace detection techniques such as ion mobility spectrometry (IMS) is an area of ...

Carbohydrate and steroid analysis by desorption electrospray ionization mass spectrometry
Chemical Communications, 2008Desorption electrospray ionization mass spectrometry (DESI-MS) is applied to the analysis of carbohydrates and steroids; the detection limits are significantly improved by the addition of low concentrations of salts to the spray solvent.

Desorption Electrospray Ionization Imaging of Small Organics on Mineral Surfaces
2014Desorption electrospray ionization (DESI)-mass spectrometry facilitates the ambient chemical analysis of a variety of surfaces. Here we describe the protocol for using DESI imaging to measure the distributions of small prebiotically relevant molecules on granite surfaces.
