Twenty years of amino acid determination using capillary electrophoresis: A review

Use of Amino Acid-Based Ionic Liquids in Capillary Electrophoresis

20 years of fatty acid analysis by capillary electrophoresis.

A review taking into account the literature reports covering 20 years of fatty acid analysis by capillary electrophoresis is presented. This paper describes the evolution of fatty acid analysis using different CE modes such as capillary zone electrophoresis, non-aqueous capillary electrophoresis, micellar electrokinetic capillary chromatography and microemulsion electrokinetic chromatography em...

Determination of L-Ascorbic Acid in Tomato by Capillary Electrophoresis

In an undergraduate bioanalytical instrumental lab, students use capillary electrophoresis to quantify L-ascorbic acid (vitamin C) in food samples. The students are tasked to prepare standards, to obtain the calibration curves, and to determine the quantity of L-ascorbic acid in tomato samples (Lycopersicon fruit). A discussion about the function of each component of a capillary electrophoresis...

Using nonequilibrium capillary electrophoresis of equilibrium mixtures for the determination of temperature in capillary electrophoresis.

Until now, all methods for temperature sensing in capillary electrophoresis (CE) relied on molecular probes with temperature-dependent spectral/optical properties. Here we introduce a nonspectroscopic approach to determining temperature in CE. It is based on measuring a temperature-dependent rate constant of complex dissociation by means of a kinetic CE method known as nonequilibrium capillary ...

Microfabricated capillary electrophoresis amino acid chirality analyzer for extraterrestrial exploration.

Chiral separations of fluorescein isothiocyanate-labeled amino acids have been performed on a microfabricated capillary electrophoresis chip to explore the feasibility of using such devices to analyze for extinct or extant life signs in extraterrestrial environments. The test system consists of a folded electrophoresis channel (19.0 cm long x 150 microns wide x 20 microns deep) that was photoli...
