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 ...
Determination of ellagic acid by capillary electrophoresis in Argentinian wines
(Wiley VCH Verlag, 2018-07)
Rising interest in ellagic acid (EA) present in functional foods is supported by its antimutagenic, anticarcinogenic, antiviral, antibacterial and antioxidative effects. The present approach presents for the first time the ...
A simple and fast method for chlorsulfuron and metsulfuron methyl determination in water samples using multiwalled carbon nanotubes (MWCNTs) and capillary electrophoresis
(Elsevier Science, 2010-11)
A new method to determine metsulfuron methyl (MSM) and chlorsulfuron (CS) in different water samples was developed. It consists in a solid phase extraction (SPE) procedure using multiwalled carbon nanotubes (MWCNTs) as ...
Temperature Dependence of Acidity Constants, a tool to affect separation selectivity in capillary electrophoresis
(Elsevier Science, 2007-07)
The mathematical models of migration and dispersion in capillary zone electrophoresis of small molecules form a sound basis for separation strategies of complex mixtures. It turned out that the key property is the effective ...
Analysis of phenolic compounds in onion nectar by miniaturized off-line solid phase extraction-capillary zone electrophoresis
(Royal Society of Chemistry, 2014-07-16)
Onion is an important vegetable crop which depends heavily on cross-pollinating insects for any significant increase in seed production. Nectar is the most important floral reward offered by plants. Minor components such ...
Simultaneous determination of saccharin and aspartame in commercial noncaloric sweeteners using the PLS-2 multivariate calibration method and validation by capillary electrophoresis
(American Chemical Society, 2008-10)
A new method to determine a mixture for sweetener sodium saccharin and aspartame in commercial noncaloric sweeteners is proposed. A classical full factorial design for standards was used in the calibration step to build ...
Effect of Background Electrolyte on the Estimation of Protein Hydrodynamic Radius and Net Charge through Capillary Zone Electrophoresis
(Wiley VCH Verlag, 2005-12)
Two physicochemical models are proposed for the estimation of both hydrodynamic radius and net charge of a protein when the capillary zone electrophoretic mobility at a given protocol, the set of pK of charged amino acids, ...
