Open the CIPO recordAbstract From the Canadian patent
An apparatus and method for performing ion mass spectrometry via Fourier transform ion cyclotron resonance utilizes a superconducting magnet with a bore and a vacuum chamber received in the magnet bore. The superconducting magnet and the vacuum chamber are enclosed in a cooling chamber and cooled together until the operating temperature of the magnet is reached. Because the temperature of the vacuum chamber is similar to the operating temperature of the superconducting magnet during operation the wall of the vacuum chamber is , sufficiently cold to function as a cryogenic vacuum pump to provide enhanced pumping of the volume in the vacuum chamber. The approach of cooling the vacuum …

Why it's free to use
- Filed January 8, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 8, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 8, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
