摘要
Abstract
The separation of anionic compounds by strong anion-exchange capillary electrochromatography (SAX-CEC) was carried out. It was found that the analytes could be absorbed onto the stationary phase, and this would lessen the retention factors (k) of the analytes, thus the column separation capability decreased. For the acidic compounds, k increased with increase of applied voltage. And the change of the applied voltage could provide different separation selectivity for the solutes. The separation with different eluent was studied. It showed that the logarithm of the capacity factor linearly decreased with increase of the logarithm of the ionic strength. The different retention behavior of the anionic compounds in SAX-CEC and CE was also studied关键词
