Micellar electrokinetic chromatography (MEKC) is a chromatography technique used in analytical chemistry. It is a modification of capillary electrophoresis (CE), extending its functionality to neutral analytes, where the samples are separated by differential partitioning between micelles and a surrounding aqueous buffer solution.
Chiral column chromatography is a variant of column chromatography that is employed for the separation of chiral compounds, i.e. enantiomers, in mixtures such as racemates or related compounds. The chiral stationary phase (CSP) is made of a support, usually silica based, on which a chiral reagent or a macromolecule with numerous chiral centers is bonded or immobilized.
Electrochromatography is a chemical separation technique in analytical chemistry, biochemistry and molecular biology used to resolve and separate mostly large biomolecules such as proteins. It is a combination of size exclusion chromatography and gel electrophoresis. These separation mechanisms operate essentially in superposition along the length of a gel filtration column to which an axial electric field gradient has been added. The molecules are separated by size due to the gel filtration mechanism and by electrophoretic mobility due to the gel electrophoresis mechanism. Additionally there are secondary chromatographic solute retention mechanisms.
Instrumental analysis is a field of analytical chemistry that investigates analytes using scientific instruments.
The Eastern Analytical Symposium (EAS) and Exposition is an American organization that sponsors a Symposium and Exposition generally held in Princeton, New Jersey, every November. The Symposium is attended by over 2000 scientists and typically contains several hundred papers by the world's leading authorities on analytical chemistry.
John Calvin Giddings was a Distinguished Professor of chemistry at the University of Utah. Giddings received a B.S. degree from Brigham Young University in 1952 and a PhD from the University of Utah in 1954. Following postdoctoral work at the University of Utah and the University of Wisconsin, he joined the faculty of the University of Utah as assistant professor of chemistry in 1957. He became associate professor in 1959, research professor in 1962, and professor in 1966. Giddings authored or co-authored more than 400 publications and edited 32 books in the field of chemistry. He was executive editor of the journal Separation Science and Technology, and the editor of the series Advances in chromatography.
In chemical analysis, capillary electrochromatography (CEC) is a chromatographic technique in which the mobile phase is driven through the chromatographic bed by electro-osmosis. Capillary electrochromatography is a combination of two analytical techniques, high-performance liquid chromatography and capillary electrophoresis. Capillary electrophoresis aims to separate analytes on the basis of their mass-to-charge ratio by passing a high voltage across ends of a capillary tube, which is filled with the analyte. High-performance liquid chromatography separates analytes by passing them, under high pressure, through a column filled with stationary phase. The interactions between the analytes and the stationary phase and mobile phase lead to the separation of the analytes. In capillary electrochromatography capillaries, packed with HPLC stationary phase, are subjected to a high voltage. Separation is achieved by electrophoretic migration of solutes and differential partitioning.

Chiral analysis refers to the quantification of component enantiomers of racemic drug substances or pharmaceutical compounds. Other synonyms commonly used include enantiomer analysis, enantiomeric analysis, and enantioselective analysis. Chiral analysis includes all analytical procedures focused on the characterization of the properties of chiral drugs. Chiral analysis is usually performed with chiral separation methods where the enantiomers are separated on an analytical scale and simultaneously assayed for each enantiomer.
