ABSTRACT:
A method and apparatus for identification of activating ions by collisions is described. The method uses a plurality of linear ion taps and a plurality of sources of ions and a mass measuring device. A first source is operated to dispense first ions into first trap, where the ions may be kinetically cooled. A second source is operated to dispense second ions into the first trap, where the first and the second ions are stored. Ions in the first trap are ejected so as to enter a second trap, where the ions are stored prior to mass spectrometry. The apparatus may use quadrupole rods to form the ion traps, and the voltage and pressure differences between the first and second traps are controllable values.
