A method for analyzing data from a mass spectrometer comprising obtaining calibrated continuum spectral data by processing raw spectral data; obtaining library spectral data which has been processed to form calibrated library data; and performing a least squares fit preferably using matrix operations , (equation 1) between the calibrated continuum spectral data and the calibrated library data to determine concentrations of components in a sample which generated the raw spectral data. A mass spectrometer system (Fig. 1) that operates in accordance with the method a data library of transformed , mass spectra and a method for producing the data library.

Why it's free to use
- Filed April 28, 2004 and granted June 30, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 28, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 28, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
