[Potential use of infrared spectroscopy for the quantitative characterization of the chemical composition of Salmonella typhi preparations].
The possibility of using infrared spectroscopy for the evaluation of the chemical composition of S. typhi preparations is shown. The existence of a clear-cut correlation between the optical density of adsorption bands in the region between 1,665 and 1,100 cm-1 and the content of protein, polysaccharide and nucleic acids in the preparations subjected to analysis has been revealed. The character of changes in the infrared spectra of the preparations at different stages of deep cultivation has been studied.
