| Abstract: | In this article, PLS combined with near-infrared spectroscopy method was used for non-destructive quantitative analysis of diclofenac sodium powder samples, and the best mathematic calibration models were built simultaneously. Furthermore, the PLS models that established with different pretreated spectra were designed and compared, and the affection on the prediction ability of PLS model that caused by the numbers of principal component were discussed. In this model, the prediction set was predicted, and the results were satisfied. |
