Abstract: Apparatus, systems, and methods for reducing or eliminating crosstalk in ion mobility spectrometers are provided. In some aspects, the apparatus, systems, and methods can reduce or eliminate crosstalk without significantly increasing the overall capacitive load of the ion mobility system. In accordance with various aspects of the applicant's teachings, cross talk compensation circuits are disclosed herein that address resulting issues in RF pickup and/or crosstalk in ion mobility spectrometers used with high-sensitivity downstream mass spectrometers such as mass spectrometers having high velocity gas interfaces that can be coupled to the ion mobility spectrometer.
