摘要：

The polyacrylamide gels described here have the ability to separate uncharged substances of comparatively low molecular weight due to the built-in, negatively charged functional groups. The functional groups permit the development of electroosmotic now under the influence of a high voltage, which makes possible capillary electrochromatographic separations of uncharged compounds. The effects of gel compositions on the column performance were examined. Migration time reproducibilities of 0.43% RSD or less were found with the gel-filled capillary columns. Possible insight into the separation mechanisms is discussed.
