Pulsed NMR system for industrial purposes comprising sample throughput system (P L1, V1, V2) magnetic field adjustment, (120 124) and thermal adjustment (134-138 and 142-146). The resonance is established by a coil (100) excited by a transceiver, (104) and interacting with the sample and the magnetic field at resonance to establish received and digitized free induction decay curve forms (C) which are automatically analyzed into Gaussian and exponential components -- providing simplified high speed computation means with repetitive test sequence and thermal controls that systematically minimize errors to assure reliable determination of target nuclei quantities in successive samples from an …

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents, and the Claude kit works from them.
Why it's free to use
- Filed March 19, 1991 and granted January 19, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 19, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
