Open the CIPO recordAbstract From the Canadian patent
The system consists of light source (2) a monochrometer (4), one, or more etalons or other samples (7) a detector (8) and a, computer (10) to store reference spectra provide a read out, indicative of the spectrum and to change the instrument response. A transfer function is used to recharacterize the instrument's wavelength position and intensity response to match the actual spectrum with the standard spectrum. In one embodiment the etalon (7) is, used in series with the unknown sample (9). A spectrum of the unknown sample and etalon (7) is created and is extracted from the spectrum of the unknown sample (9) alone to provide the actual spectrum of the instrument response to the etalon (7) …

Why it's free to use
- Filed August 6, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 6, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
