DESI TOF imaging at 30 scans/sec was achieved using the SYNAPT G2-Si and Xevo G2-XS. Despite a decrease in sensitivity, the image quality and MS resolution were not affected by the increase in acquisition speed. It was demonstrated that DESI imaging at up to 10 scans/sec was feasible with ion mobility separation. Fast transfer MS/MS IMS DESI imaging allowed the generation of ion images for isobaric species at a scan rate of 6 scans/sec Combining fast DESI imaging with "Real time" viewer software allowed the visualisation of 4 m/z on the fly to assess the quality of the experiment.
