## Abstract The packed capillary column is one type of microcolumn. It is used increasingly in liquid chromatography, supercritical fluid chromatography, and multidimensional chromatography. In order to attain high efficiency with packed capillary columns, reliable column preparation methods must b
This paper is a theoretical study of electroosmotic flow through various model packings to understand the mechanisms of capillary electrochromatography ลฝ . CEC and to take full advantage of CEC. Two different equations for electroosmotic flow velocity are described and compared with each other throu
