Apparatus and method for adjustment of ion separation resolution in FAIMS

摘要

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.
