Microchip electrophoresis tools for the analysis of small molecules
Microchip electrophoresis (ME) results from miniaturization of capillary electrophoresis (CE) to a microfabricated separation device. Both techniques have common characteristics, but in some aspects, the microfluidic ...
Direct detection of underivatized chitooligosaccharides produced through chitinase action using capillary zone electrophoresis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Capillary electrophoresis with capacitively coupled contactless conductivity detection was successfully used to quantify N-acetylglucosamine and five N-acetyl-chitooligosaccharides (C2-C6) produced after reaction with a ...

Quantitative Determination of Gemifloxacin Mesylate in Tablets by Capillary Zone Electrophoresis and High Performance Liquid Chromatography
(COLEGIO FARMACEUTICOS PROVINCIA DE BUENOS AIRES, 2011)
The aim of this study was to develop and validate selective and sensitive methods for quantitative determination of an antibacterial agent, gemifloxacin, in tablets by high performance liquid chromatography (HPLC) and ...
Cloud point preconcentration prior to capillary zone electrophoresis: Simultaneous determination of platinum and palladium at trace levels
(Wiley VCH Verlag, 2005-09)
The incorporation of a cloud point extraction (CPE) step prior to capillary electrophoresis (CE) for simultaneously determining platinum and palladium at sub-μg/L levels is presented and evaluated. The analytes were extracted ...
Phenolic composition in grape (Vitis vinifera L. cv. Malbec) ripened with different solar UV-B radiation levels by capillary zone electrophoresis
(American Chemical Society, 2008-04-16)
The responses of Vitis vinifera L. cv. Malbec to different solar ultraviolet-B radiation (UV-B) levels were assessed in two contrasting situations, under sunlight with full UV-B (+UV-B) and filtered UV-B (-UV-B), in three ...
Simultaneous determination of cloramphenicol, salicylic acid and resorcinol by capillary zone electrophoresis and its application to pharmaceutical dosage forms
(Elsevier Science, 2003-10)
This study demonstrates the separation of active ingredients in acne formulations (salicylic acid, cloramphenicol and resorcinol in presence of azulene) by capillary zone electrophoresis. Factors affecting their separations ...
Determination of lead in human saliva by combined cloud point extraction-capillary zone electrophoresis with indirect UV detection
(Elsevier Science, 2006-02)
A micelle-mediated phase separation without added chelating agents to preconcentrate trace levels of lead in human saliva as a prior step to its determination by capillary electrophoresis has been developed. The enrichment ...
Development and validation of a method for quantitative determination of econazole nitrate in cream formulation by capillary zone electrophoresis
(ELSEVIER SCIENCE BV, 2008)
A simple, fast, inexpensive and reliable capillary zone electrophoresis (CZE) method for the determination of econazole nitrate in cream formulations has been developed and validated. Optimum conditions comprised a pH 2.5 ...
