Abstract
A method and an apparatus is disclosed for selectively transmitting ions with a FAIMS analyzer in which a flow of carrier gas of a mixed composition is provided. Ions that are transmitted at a same combination of applied potentials when a first carrier gas is provided are in certain cases transmitted at different combinations of applied potentials when a second other carrier gas having a different composition is provided.
