A New Method of Trapping Ions Injected into the Quadrupole Ion Trap and Construction

Abstract (Set) This is a method in which ions formed by matrix-assisted laser desorption/ionization (MALDI) and other methods which form ions outside an ion trap mass spectrometer are then transmitted into and held by the ion trapping field. The method involves a dynamic trapping field in which the trapping voltage is increased during ion introduction. Description (Set) Proposed Use (Set) ion trap mass spectrometers, biological research instrumentation, bioagent and chemical detection
