ABSTRACT:
Disclosed is a high field asymmetric waveform ion mobility spectrometer (FAIMS) having a side-to-side electrode geometry. The FAIMS includes an inner electrode (102) having a length and an outer surface that is curved in a direction transverse to the length. The FAIMS also includes an outer electrode (104) having a length, a channel extending therethrough along at least a portion of the length, and a curved inner surface, a portion of the length of the outer electrode overlapping a portion of the length of the inner electrode so as to provide an analyzer region therebetween. The outer electrode has an ion inlet (114) for introducing ions from a source of ions into the analyzer region and an ion outlet (112) for extracting ions from the analyzer region, the ion inlet and the ion outlet being disposed on opposing sides of the outer electrode. The FAIMS is characterized in that at least one of the inner and outer electrodes is shaped such that a width of the analyzer region in the vicinity of the ion outlet is other than a width of the analyzer region in at least one other region.
