Open the CIPO recordAbstract From the Canadian patent
A mass spectrometer comprises an ion source for supplying sample ions for analysis a linear ion trap, a deflection lens and an electrostatic trap mass analyzer. The linear ion trap extends between an entrance end for receiving sample ions and an axially opposed exit end through which sample ions are released and travel along a first axis. The deflection lens is positioned downstream in the ion path from the linear ion trap and deflects the sample ions along a second axis displaced from the first axis. The electrostatic trap mass analyzer is positioned downstream of the deflection lens for mass analyzing the sample ions. Sample ions having high energies are prevented from streaming from the …

Why it's free to use
- Filed March 20, 2002 and granted November 27, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 20, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 20, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
