Shimadzu is introducing the LCMS-9050 Q-TOF, a quadrupole time-of-flight (Q-TOF) mass spectrometer system. A proprietary high precision temperature control system inhibits even tiny mass variations caused by external factors so that the system can be used to measure accurate mass values without worrying about mass calibration. The ultra-stable polarity switching technology enables the simultaneous analysis of positive and negative ions, contributing to new applications development and heightened analysis efficiency. Optional equipment includes the DPiMS™ probe electrospray ionisation unit, SICRIT ion source for LC/GC/direct analysis, MALDI for mass spectrometry imaging and optional fragmentation.
