Systems and methods of suppressing unwanted ions

摘要

Certain embodiments described herein are directed to systems including a cell downstream of a mass analyzer. In some instances, the cell is configured as a reaction cell, a collision cell or a reaction/collision cell. The system can be used to suppress unwanted ions and/or remove interfering ions from a stream comprising a plurality of ions.

主权项

1. A system comprising:
an ion source; ion optics fluidically coupled to the ion source; a mass analyzer fluidically coupled to the ion optics, in which the mass analyzer is the only mass analyzer in the system; a cell fluidically coupled to the mass analyzer and downstream of the mass analyzer; and a detector fluidically coupled to the cell.
