Ion mobility system comprising two IMS cells

An ion mobility spectrometer sysem includes two cells (1) and (2) driven by a driven unit (12) so that the cells operate at opposite polarities and are switched between different polarities either at regular intervals or in response to detection of a substance in one cell. Two reagents are supplied...

Summary:An ion mobility spectrometer sysem includes two cells (1) and (2) driven by a driven unit (12) so that the cells operate at opposite polarities and are switched between different polarities either at regular intervals or in response to detection of a substance in one cell. Two reagents are supplied to both cells (1) and (2), one promoting detection of a substance in the positive mode and the other promoting detection of a substance in the negative mode so that there is no need to switch reagents when the polarity changes.
