Abstract

The recent introduction of ambient ionization mass spectrometry techniques has generated an important progress in the direct analysis of organic compounds. Specifically, desorption electrospray ionization (DESI), one of the most frequently used ambient techniques, allows the analysis on the sample surface directly or with minimal sample manipulation. Thus, the analysis is performed in few seconds and is applicable to complex samples, especially when using high resolution mass spectrometry (HRMS). This paper presents some examples showing the applicability of DESI-HRMS for the screening analysis of organic compounds in complex samples.
