Imaging mass spectrometry is a mapping technique used on samples where the spatial resolution of differing masses is of key importance.
Imaging Mass Spec
Detailed Description
A mass spectrometer coupled to a powerful laser or DESI source. A laser or a solvent mix is directed to the surface of a plate which contains the sample. The sample is moved according to a pre-programmed raster and mass spectra are taken at each point. Post-processing of the continuous mass spectra allows the spatial resolution to be deconvoluted and an image of the differing masses extracted for each raster point.
• Results are resolved in spatial coordinates in addition to masses
• Can achieve very high mass for a MS system
• Easy sample preparation
• Rough surfaces can be analysed
• MALDI Laser source
• DESI source gives atmospheric pressure analysis with minimal preparation
• HDI Software for programming and post-processing image manipulation
• Modes can be switched in roughly 2 hours
