Nonaqueous Capillary Electrophoresis

Analytical Chemistry, 1994
This paper reports an investigation of performing capillary electrophoresis (CE) in formamide. Formamide has a higher dielectric constant than water and can solubilize many supporting electrolytes. It is commonly used in mixtures with water in electrophoretic buffers.

Capillary electrophoresis of carbohydrates

Glycobiology, 1994
Capillary electrophoresis has emerged as a highly promising technique for the analysis of mono- and oligosaccharides. The approaches developed for overcoming the lack of chromophoric and fluorophoric functions in most carbohydrates involve the use of indirect photometric detection, amperometry, mass spectrometry, and precolumn derivatization with ...

Multidimensional capillary electrophoresis

ELECTROPHORESIS, 2014
Multidimensional separation where two or more orthogonal displacement mechanisms are combined is a promising approach to increase peak capacity in CE. The combinations allow dramatic improvement of analytical performance since the total peak capacity is given by a product of the peak capacities of all methods.

Capillary electrophoresis of pesticides

ELECTROPHORESIS, 1997
AbstractPesticides are important and diverse environmental and agricultural species. Their determination in pesticide formulations, in feed and food, and in complex environmental matrices (e.g., water, soil, sludge, sediments, etc.) often requires separation methods of high efficiency, unique selectivity and high sensitivity.

Forensic capillary electrophoresis

TrAC Trends in Analytical Chemistry, 1996
Abstract Capillary electrophoresis (high-performance electrophoresis) has recently become established as a versatile and powerful separation technique. It has a broad applicability and can be used with a variety of detection systems. An introduction is given to this analytical technique, then some applications to forensic problems are discussed.

Detection in capillary electrophoresis

Electrophoresis, 2000
A review of the four major, on-line, capillary electrophoresis (CE) detection modalities is presented. It is shown that each detection method, fluorescence, absorbance (conventional and nonconventional), electrochemical and refractive index, have distinct advantages and limitations when applied to analysis in a CE format.

Affinity capillary electrophoresis

ELECTROPHORESIS, 1997
AbstractThe application of affinity capillary electrophoresis (ACE) to the study of molecular interactions is reviewed. ACE appears to be a sensitive, versatile and convenient tool to obtain reliable data on binding constants and stoichiometries of interacting systems using the Hummel‐Dreyer method and variants thereof.

Derivatization in Capillary Electrophoresis

2016
Capillary electrophoresis is a well-established separation technique in analytical research laboratories worldwide. Its interesting advantages make CE an efficient and potent alternative to other chromatographic techniques. However, it is also recognized that its main drawback is the relatively poor sensitivity when using optical detection.

Cyclic capillary electrophoresis

ELECTROPHORESIS, 2002
A strategy is described here for increasing both the resolution and the flexibility of capillary electrophoresis performed in a sieving medium of ungelled polymer. This strategy is based on analysis and, sometimes, re-analysis that is done in several stages of constant-field electrophoresis. Enhancement-stages are between the analysis-stages.

Capillary Electrophoresis of Hemoglobin

Clinical Chemistry and Laboratory Medicine, 2003
Capillary electrophoresis (CE) has been used in a variety of in-house capillary isoelectric focusing (CIEF) and capillary zone electrophoresis (CZE) assays for the detection of hemoglobin (Hb) variants and the quantitation of HbA2 and HbF. A commercial kit has also been produced for the analysis of hemoglobin variants and thalassemia screening.
