Description
SYNAPT G2-Si Imaging Mass Spectrometer
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
Bruker AutoFlex MALDI-MS
This Matrix Assisted Laser Desorption Ionisation – Mass Spectrometer (MALDI-MS) is suitable for a wide range of samples from intact proteins to polymers. Matrix selections is key to obtain good results. It is a destructive technique. As the mass spectrometer is coupled to a powerful laser, it is capable of measuring high mass ranges that are not possible with a traditional ESI/APCI source.
