Abstract:The non-destructive determination of cimetidine in tablets was proposed by near-infrared spectroscopy and partial least squares (PLS) method. The best mathematic model was established. The effects of the wavelength interval and the numbers of principal components on the prediction of PLS were discussed.
Keywords:Near-infrared spectroscopy  Partial Least Squares  Cimetidine  Non-destructive quantitative analysis
