Open the CIPO recordAbstract From the Canadian patent
The application describes a method for predicting chemical or biological properties, e.g. toxicity, mutagenicity etc. of complex multicomponent , mixtures from 2D separation date e.g. GC-MS. The data are resolved into peaks (C) and spectra (S) for individual components by an automated curve resolution procedure (GENTLE). The resolved peaks are then integrated and the characteristic area, separation parameter and associated spectrum combined to yield a predictor matrix (X), which is used as input to a multivariate regression model. Partial least squares (PLS) are used to correlate the 2D separation date for a training set to the measured property. The regression model can then be …

Why it's free to use
- Filed July 4, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 4, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
