mass analyzer Frank Gibson PERSON: Daniel Schober A Mass analyzer is a device that separates ions according to their mass-to-charge ratio. All mass spectrometers are based on dynamics of charged particles in electric and magnetic fields in vacuum where the two laws of Lorentz force law and Newton's second law of motion apply. http://en.wikipedia.org/wiki/Mass_spectrometry#Mass_analyzer The mass analyzer of the Voyager-DE(tm) STR Biospectrometry Workstation mass analyzer measurement device material separation device
