Abstract
A sample solution containing protein is irradiated with excitation light of a single wavelength which is emitted from a light source, so that light scattered from the sample solution is received and separated into its spectral components in a spectroscope, thereby obtaining light scattering spectra. Protein is quantitatively measured through intensity of a light scattering spectrum in a shift wavenumber of 100 to 3100 cm.sup.-1 with respect to the excitation wavelength among the light scattering spectra or an integral value in a proper range therein. As to a body fluid sample, the sample is irradiated with excitation light and Raman scattering spectral intensity values are measured at a plurality of wavenumbers in an arbitrary wavenumber range, and a plurality of components in the sample are analyzed simultaneously by multivariate regression analysis.
