Capillary electrophoresis (CE) is a modern separation method, which represents a competent alternative to liquid chromatography. The CE separation is performed in very thin silica capillaries. Advantages of CE are the high separation efficiency, low sample consumption and short time of analysis compared to liquid chromatography. CE represents a strong tool for analysis of body fluids.

        Key words: capillary electrophoresis, liquid chromatography, body fluids, low molecular compounds, proteins, amino acids.
