摘要：
A rapid, simple and reliable capillary isotachophoresis (ITP) with conductivity detection was used to determine the trace quantities of organic compounds of selenium - selenomethionine (Se-Met) and selenocystine (Se-Cys) - in various types of beer. The content of Se-Met in beer is between 59.10(-3) g dm(3) (Czarne beer) and 510.10(-3) g dm(3) (Zywiec Porter beer), while the content of Se-Cys ranges from 84.10(-3) g dm(3) (Czarne) to 247.10(-3) g dm(3) (Zywiec Porter).
