摘要: An apparatus for multiplexing ions from a plurality of ionization sources includes a FAIMS analyzer including an inner electrode and an outer electrode, the outer electrode having a plurality of spaced-apart ion inlet orifices and a single ion outlet orifice. A plurality of non-trapping FAIMS analyzers is disposed adjacent to the FAIMS analyzer. Each non-trapping FAIMS analyzer of the plurality of non-trapping FAIMS analyzers has a single ion outlet orifice in communication with one ion inlet orifice of the plurality of ion inlet orifices of the FAIMS analyzer, and each non-trapping FAIMS analyzer has a single ion inlet orifice for supporting introduction of ions into the non-trapping FAIMS. An electrical controller is provided in communication with the FAIMS, for providing conditions within the FAIMS for supporting transmission of at least some of the ions introduced into the FAIMS from one of the non-trapping FAIMS and for not supporting transmission of substantially all of the ions introduced simultaneously into the FAIMS from the other one of the non-trapping FAIMS.
