Abstract: An apparatus for separating ions includes a FAIMS analyzer region having a first ion inlet for introducing ions into the FAIMS analyzer region. An ion outlet from the FAIMS analyzer region is provided for extracting a subset of the ions that is selectively transmitted along an average ion flow path defined through the FAIMS analyzer region. The apparatus also includes an actuator for controllably varying a length of the average ion flow path through the FAIMS analyzer region.

Abstract: An ion introduction system for selecting ions from one of two separate ionization sources of ions is provided. The system includes a plate having a hole formed therethrough, the plate for being disposed adjacent an ion introduction region of a gas phase ion analyzer such that the hole is selectively movable between a first location in which the hole is adjacent to a first ionization source of ions for supporting introduction of ions from the first ionization source of ions into the gas phase ion analyzer, and a second location in which the hole is adjacent to a second ionization source of ions for supporting introduction of ions from the second ionization source of ions into the gas phase ion analyzer. The system also includes a drive mechanism for driving the plate between a first position in which the hole is at the first location and a second position in which the hole is at the second location.
