Overview of capillary electrophoresis and capillary electrochromatography

Journal of Chromatography A, 1999
This paper provides an overview on the current status of capillary electrophoresis (CE) and capillary electrochromatography (CEC). The focus is largely on the current application areas of CE where routine methods are now in place. These application areas include the analysis of DNA, clinical and forensic samples, carbohydrates, inorganic anions and ...

Recent progress in capillary electrochromatography

Electrophoresis, 2000
Capillary 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 ...

Semipreparative Capillary Electrochromatography

Analytical Chemistry, 2001
Capillaries with inner diameters of 550 microm have successfully been packed with 1.5-microm octadecyl silica particles using frits made of macroporous polymers by the UV photopolymerization of a solution of glycidyl methacrylate and trimethylolpropane trimethacrylate. This type of frit is found superior to one made of low-melting point poly(styrene-co-

Theory of capillary electrochromatography

Journal of Chromatography A, 2001
The present state of the theory of capillary electrochromatography (CEC) is reviewed. Emphasis is placed on electroosmosis and the electrical double layer, and the generally good understanding of the factors affecting the electroosmotic flow in CEC columns.

Instrumentation for capillary electrochromatography

Journal of Chromatography A, 2000
One of the reasons for the immense interest in capillary electrochromatography (CEC) is its feature to combine chromatographic selectivity with the high efficiency and the miniaturization potential of capillary electrophoresis (CE). The capability of commercial CE instruments to run CEC has enforced the readiness of users and researchers to work on ...

Applications of capillary electrochromatography

Electrophoresis, 1999
Applications performed by capillary electrochromatography (CEC) in all its modes, namely packed column CEC (packed-CEC), open tubular CEC (OT-CEC) and pressure-assisted CEC (pseudo-CEC), and published by June 1999 are reviewed. The review is divided into (i) separation of neutral, acidic and basic analytes with the main goal of evaluating column and ...

Advances in capillary electrochromatography

ELECTROPHORESIS, 1997
AbstractCapillary 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.

Fritless capillary electrochromatography

Electrophoresis, 1999
The preparation of packed capillaries with stable frits of good quality can be a hurdle to obtain efficient separations in capillary electrochromatography (CEC). Especially with particles smaller than 3 microm, frit preparation is cumbersome. Highly efficient separations using packed capillaries without frits are presented.

Capillary Electrochromatography of Cannabinoids

Analytical Chemistry, 1998
The applicability of capillary electrochromatography (CEC) with photodiode array UV detection for the analysis of cannabinoids is presented. Baseline separation of seven cannabinoids (cannabigerol, cannabidiol, cannabinol, delta-9-tetrahydrocannabinol, delta-8-tetrahydrocannabinol, cannabichromene, delta-9-tetrahydrocannabinolic acid) is obtained using

Nanoinjector for Capillary Electrophoresis and Capillary Electrochromatography

Analytical Chemistry, 2003
A 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.
