ABSTRACT

The aim of the research was to modify the Quyang and Wu method for determination of selenomethionine level in selenium yeast. Modification concerned the application of capillary column for chromatographic separations and addition of the internal standard (undecanoic acid methyl ester) to the sample before analysis. The use of capillary column in analytical process significantly improved the separation of components into single, well-shaped (symmetrical) peaks, facilitating the quantitative measurements.
