A comparison of MS based imaging using DESI, MALDI and SIMS

This poster relates to work carried out under project O3 of the NMS Chemical and Biological Metrology programme.

Mass spectrometry based imaging techniques such as desorption electrospray (DESI) and MALDI (matrix assisted laser desorption ionisation) imaging are proving to be very useful tools in an increasing number of application areas such as forensics (e.g. analysis of inks) and biochemistry (e.g. detection of cancer biomarkers). These techniques complement the more established SIMS imaging technique for surface analysis. The poster describes all three techniques, and assesses the advantages and limitations of each technique.

The poster was presented at the 56^th ASMS (American Society for Mass Spectrometry) conference on mass spectrometry and allied topics held in Denver, Colorado, US on 1-5^th June 2008.
