| Abstract: | This paper studied the near infrared spectra of liquid samples.The plots of weights at each wavelength showed the spectral characteristics of pure materials.The samples could be classified by using plots of the scores of their first principal components.The principal component regression of samples was made.The obtained results were identical with the reference analytical values.The advantages of near infrared spectroscopy,combined with principal component analysis,lie in its nondectructivity for samples and suitability for on line measurements. |
