    • A method and apparatus for identification of activating ions by collisions is described. The method uses a plurality of linear ion traps and a plurality of sources of ions and a mass measuring device. A first source is operated to dispense first ions into a 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.
    • 描述了通过碰撞识别激活离子的方法和装置。 该方法使用多个线性离子阱和多个离子源和质量测量装置。 操作第一源以将第一离子分配到第一阱中,其中离子可以被动力学冷却。 操作第二源以将第二离子分配到第一阱中,其中存储第一和第二离子。 第一个陷阱中的离子被排出,以便进入第二个陷阱,其中离子在质谱之前被储存。 该装置可以使用四极杆形成离子阱,并且第一和第二陷阱之间的电压和压力差是可控的值。
