Abstract
To analyze humic substances by capillary electrophoresis diluted humic acid (HA) solutions were used as a background electrolyte, resulting in the improved reproducibility of the analysis by suppressing the analyte interactions with capillary walls. Two HA solutions were investigated: standard HA solution and the Baltic Sea sediment HA extract. Characteristic shape electropherograms were obtained. Areas of the characteristic regions correlated linearly with the concentration of the injected HA sample.
