A Raman spectrometry apparatus that is capable of measuring and compensating for variabilities in the apparatus comprises a source of substantially monochromatic radiation means for simultaneously interfacing the radiation with a sample and a reference material means, for simultaneously acquiring at more than one wavelength a convolved Raman spectrum of the sample and the convolved spectrum of the reference material, and means for determining the convolution function of the convolved spectra and applying the convolution function to adjust the convolved Raman spectrum of the sample to produce thereby the standard Raman spectrum of the sample. A method for obtaining the standard Raman …

Why it's free to use
- Filed May 15, 1995 and granted March 7, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 15, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 15, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
