Desorption Electrospray Ionization (DESI) MS – A powerful tool for chemical and materials surface analysis

Desorption ElectroSpray Ionization (DESI) is a well-established direct ionization technique for coupling with mass spectrometry. DESI mass spectrometry is a technique that allows chemical information to be obtained directly from a wide range of surfaces. DESI imaging provides information on the spatial distribution of molecules at or near the surface. DESI provides beautiful and information-rich images that allow scientists to answer the fundamental question: "Where is this component in my sample?"

Over the past decade DESI MS has gained widespread use by researchers in the analysis of peptides, proteins, drugs and metabolites in clinical and biomedical research settings. DESI MS application in chemical and materials analysis has perhaps in the past been overlooked but the techniques offers advantages over other materials surface analysis techniques such as MALDI MS and SIMS.

In this webinar we will take a look at some materials analysis applications developed within waters and highlight technology improvements of the new DESI XS source that translate into tangible benefits in surface analysis by Mass Spectrometry.
