Abstract. In this paper an analysis of the blood plasma spectrum for different mammals is performed in order to establish the relationship between protein concentration and their absorbance in the UV region. We found a direct dependence of these quantities correlating the spectra and the refractive index measured for the same protein concentrations. This suggests that the specific properties and protein concentration of plasma at different mammalian species influence the blood behavior.
Key words: plasma chromophores, absorption spectra, protein band.
