Development of a Novel Mass Spectrometer with High Resolving Power for LC/MS Analyses of Biological Molecules
We have developed a novel multi-turn TOF-MS (MTOF). This system avoided the "overtaking " that has been encountered in conventional MTOF, and achieved high resolving power while keeping its size compact. We constructed LC-MTOF-MS and evaluated the performance. Mass resolving power higher than 150k (FWHM) and instrument detection limit of approximately 3 amol were achieved. Furthermore, MS analyses of biological molecules were performed. Isotopic peaks of cytochrome c (approximately 12kDa, 8+) were clearly separated.
