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 ...

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 ...

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 ...

Electrode‐assisted desorption electrospray ionization mass spectrometry

Journal of Mass Spectrometry, 2010
AbstractA new ion source has been developed for rapid, noncontact analysis of materials at ambient conditions. The method provides desorption of analytes under ambient conditions directly from different surfaces with little or no sample preparation. The new method, termed electrode‐assisted desorption electrospray ionization (EADESI), is on the basis ...

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.

Infrared laser-assisted desorption electrospray ionization mass spectrometry

The Analyst, 2008
We have used an infrared laser for desorption of material and ionization by interaction with electrosprayed solvent. Infrared laser-assisted desorption electrospray ionization (IR LADESI) mass spectrometry was used for the direct analysis of water-containing samples under ambient conditions.

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 ...
