Open the CIPO recordAbstract From the Canadian patent
An ion mobility spectrometer system includes two cells (1) and (2) driven by a drive 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.

Why it's free to use
- Filed June 8, 2004 and granted April 9, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 8, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 8, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
