MULTIPLE NANO-SPRAY DELIVERY SYSTEM FOR FAIMS

摘要

An apparatus for multiple nano-spray delivery of a sample to FAIMS analyz er includes a micro-machined ionization source having a plurality of discrete nozzles. At least some of the discrete nozzles of the plurality are aligned one each wit h an ion inlet of a plurality of discrete ion inlets of the FAIMS, so that ions produced at different discrete nozzles are introduced into different portions of the FAIMS analyzer region. The ions that are introduced via each ion inlet are at least partly separated prior t o adding/mixing with the ions introduced via other ion inlets. This reduces the problems of ion-ion electric repulsions that occur when ion density is high.
