Abstract
A method and an apparatus for selectively transmitting ions produced by an inductively coupled plasma ionization technique is disclosed. Ions produced within the plasma source are provided to a FAIMS analyzer within a low pressure chamber of a mass spectrometer and in fluid communication with the plasma source for receiving ions therefrom. The ions are separated in FAIMS and at least some of the ions are provided to the mass spectrometer after separation.
