Column technology in capillary electrophoresis and capillary electrochromatography

Abstract

A review of column technology in capillary electrophoresis (CE) including wall modification processes and open tubular as well as packed column formats in capillary electrochromatography (CEC) are presented. There are many approaches which can be used to solve separation problems which provide higher efficiency and/or shorter analysis times in comparison to other chromatographic techniques. However, both CE and CEC are still relatively undeveloped in comparison to a more mature method such as high performance liquid chromatography (HPLC) and improvement in column technology is changing rapidly.
