Abstract
A tandem collision/reaction cell for an inductively coupled plasma-mass spectrometry (ICP-MS) system includes a first ion guide, a second ion guide, and an intermediate electrode in the vicinity of an exit end of the first ion guide. A DC potential barrier is applied to the intermediate electrode. The cell may provide two or more stages of an ion-molecule collision process.
