Deconstructing Desorption Electrospray Ionization: Independent Optimization of Desorption and Ionization by Spray Desorption Collection

Journal of the American Society for Mass Spectrometry, 2012
Spray desorption collection (SDC) and reflective electrospray ionization (RESI) were used to independently study the desorption and ionization processes that together comprise desorption electrospray ionization (DESI). Both processes depend on several instrumental parameters, including the nebulizing gas flow rate, applied potential, and source ...

Desorption electrospray ionization of aerosol particles

Rapid Communications in Mass Spectrometry, 2007
Abstract We have applied desorption electrospray ionization to aerosol particles. Ions were formed from aerosols by merging suspended dry particles with an electrospray of solvent in a modified ion trap mass spectrometer. Dry aerosol particles were generated using a fluidized bed powder disperser and directed toward the inlet of the ...

Redox Transformations in Desorption Electrospray Ionization

International Journal of Mass Spectrometry, 2009
Abstract Redox changes occur in some circumstances when organic compounds are analyzed by desorption electrospray ionization mass spectrometry (DESI-MS). However, these processes are limited in scope and the data presented here suggest that there are only limited analogies between the redox behavior in DESI and the well-known solution-phase ...

Chemical Imaging With Desorption Electrospray Ionization Mass Spectrometry

Methods in Molecular Biology, 2010
Desorption electrospray ionization mass spectrometry (DESI-MS) is a relatively new ambient surface analysis method. This technique requires little or no sample preparation prior to the actual analysis. Along with other application areas, DESI-MS is used to obtain chemical images of different biomolecules in biological tissue sections.

Protein Analysis by Desorption Electrospray Ionization Mass Spectrometry

Mass Spectrometry Reviews
AbstractThis review presents progress made in the ambient analysis of proteins, in particular by desorption electrospray ionization‐mass spectrometry (DESI‐MS). Related ambient ionization techniques are discussed in comparison to DESI‐MS only to illustrate the larger context of protein analysis by ambient ionization mass spectrometry.

On the Use of Electrospray Ionization and Desorption Electrospray Ionization Mass Spectrometry for Bulk and Surface Polymer Analysis

Applied Spectroscopy, 2010
Electrospray ionization (ESI) and desorption electrospray ionization (DESI) mass spectrometry were for the first time compared to investigate degradation products resulting from radiolysis of polyurethane (PUR) irradiated using accelerated electrons. First, DESI optimization was performed to obtain the best results in terms of sensitivity for surface ...
