Abstract From the Canadian patent

A method and apparatus for producing a discrete particle for subsequent analysis (such as mass spectrometry) or manipulation is disclosed. A discrete particle is generated by a particle generator. A net charge is induced onto the particle by an induction electrode. The particle is delivered to a levitation device where it is then electrodynamically levitated. If the particle is a droplet, desolvation will occur leading to Coloumbic fissioning , of the droplet into smaller droplets. The movement of the levitated droplet(s) can be manipulated by an electrode assembly. The droplet(s) and the charge , thereon, can be delivered to a mass spectrometer in one aspect of the invention, …

Why it's free to use

  • Filed October 23, 2001 and granted November 19, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 23, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 23, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
