ADVANCED SAMPLE IONIZATION METHOD IN ION MOBILITY SPECTROMETER

摘要

A new method for the corona discharge ignition in ion mobility spectrometer has been developed. It substantially improves stability and increases device resolution because sample controlled ionization causes a stable flow of ion-exchange processes. The implemented circuit simplifies the design of the proposed ion source and an electronic control circuit. This controlling circuit allows forming a corona discharge without using any additional ignition electrodes.
