Advances in capillary electrochromatography
ELECTROPHORESIS, 1997AbstractCapillary electrochromatography (CEC) is a hybrid between capillary electrophoresis and high performance liquid chromatography (HPLC) that has gained popularity in recent years. CEC uses an electrically driven flow to transport the solutes through the chromatographic column.

Capillary Electrochromatography with Gradient Elution
Analytical Chemistry, 1997A capillary electrochromatograph incorporating a gradient-forming system generally employed in HPLC is described, and the use of gradient elution in reversed phase electrochromatography is demonstrated by the separation of PTH-amino acids and steroid hormones.

Recent progress in capillary electrochromatography
Electrophoresis, 2000Capillary electrochromatography (CEC) continues to captivate many separation scientists. A remarkable activity is apparent from the numerous publications in the literature using CEC. A review of the most recent progress in CEC is presented herein, covering an extensive fraction of the literature on CEC published from the year 1997 until the beginning ...

Capillary electrochromatography with macroporous particles
Journal of Chromatography A, 1999The performance of macro-porous particles in capillary electrochromatography is studied. Three reversed-phase stationary phases with pore diameters between 500 A and 4000 A have been tested for separation efficiency and mobile phase velocity. With these stationary phases, a large portion of the total flow appears to be through the pores of particles ...

Nanoinjector for Capillary Electrophoresis and Capillary Electrochromatography
Analytical Chemistry, 2003A rotary valve nanoinjector was devised for use in capillary electrophoresis (CE) and capillary electrochromatography (CEC). A fused-silica capillary tip was inserted in a small through-hole in the rotor. The narrow and short capillary tip, with an inner volume of 6-24 nL, was embedded in the hole using epoxy resin.

Immunoaffinity screening with capillary electrochromatography
ELECTROPHORESIS, 2002Highly efficient capillary electrochromatographic separations of cardiac glycosides and other steroids are presented. Employing butyl-derivatized silica particles as stationary phase resulted in a nearly three times faster electroosmotic flow (EOF) compared to capillary electrochromatography (CEC) with octadecyl silica particles.

Packing columns for capillary electrochromatography
Journal of Chromatography A, 2000Considering the current interest in capillary electrochromatography (CEC), performed in packed columns, we present the different methods used to pack capillary columns for use in CEC. General considerations on column packing are given and the column fabrication process is discussed in sufficient detail to allow instruction to those who are not ...

Stationary phases for capillary electrochromatography
Journal of Chromatography A, 2000This review summarizes the variety of stationary phases that have been employed for capillary electrochromatography (CEC) separations. Currently, about 70% of reported CEC research utilizes C18 stationary phases designed for liquid chromatography, but an increasing number of new materials (e.g., ion-exchange phases, sol-gel approaches, organic polymer ...
