| Abstract: | In this paper the simulative system of two-component mixture is used to illus-trate the effect of parameters: the spectra over-lapping, the number of calibration sam-ples, the number or wavelengths, the rate of component concentration and random erroron the prediction of results calculated by PLS and PCA.The spectral data of two-compo-nent system of food colorants also is used to illustrate how to apply simulative system toselect the parameters to determine and predict the error. |
