摘要:
A mass spectrometer is disclosed comprising a segmented quadrupole rod set ion trap for trapping ions in axial DC potential wells wherein a potential field is created at the exit of the ion trap which decreases with increasing radius in one radial direction. Ions within the ion trap are mass selectively excited in a radial direction. Ions which have been excited in the radial direction experience a potential field which no longer confines the ions axially within the ion trap but which instead acts to extract the ions and hence causes the ions to be ejected axially from the ion trap.

公开了一种包括四极杆组离子阱(2,3)的质谱仪,其中在离子阱(4,5)的出口处产生势能场,其在一个径向方向上随半径增加而减小。 离子阱(2,3)内的离子在径向方向上被质量选择性地激发。 已经在径向激发的离子经历势场,该势场不再将离子轴向限制在离子阱内,而是用于提取离子并因此导致离子从离子阱(2,3)轴向射出, 。
