Abstract
Improved methods and devices for analysis of gas phase ions via ion mobility type analyzers, particularly high field asymmetric waveform ion mobility analyzers (FAIMS), by linking gas composition and/or flow rate with the scanning of compensation voltage or asymmetric waveform amplitude are provided. Linking these parameters results in improvements in resolution, sensitivity, and selectivity. The methods and devices according to the presently disclosed subject matter provide for the improvement in resolution for specific ions without affecting the entire FAIMS spectrum.
