Abstract

Techniques for the determination of the elemental composition of dietary supplements (Multifort®, Komplivit®) are presented. It is proposed to use a state-of-the-art analytical method, total reflection X-ray fluorescence spectrometry. The differences in the sample preparation of encapsulated and not encapsulated dietary supplements are described. The effect of encapsulation on the results of the analysis is revealed. The results of qualitative and quantitative analysis are compared with the values certified by the manufacturing company.
