Rapid simultaneous determination of organic acids, free amino acids, and lactose in cheese by capillary electrophoresis.
A capillary electrophoresis (CE) method for the simultaneous separation of 11 metabolically important organic acids (oxalic, formic, citric, succinic, orotic, uric, acetic, pyruvic, propionic, lactic, and butyric), 10 amino acids (Asp, Glu, Tyr, Gly, Ala, Ser, Leu, Phe, Lys, and Trp), and lactose has been optimized, validated, and tested in dairy products. Repeatability and linearity were calcu...
متن کاملSeparation of aromatic acids, DOPA, and methyl-DOPA by capillary electrophoresis with dendrimers as buffer additives.
Polyamidoamine starburst dendrimers with terminal carboxylate groups are used as a pseudo-stationary phase in electrokinetic chromatography for separating the selected aromatic amino acids phenylalanine, phenylglycine, homophenylalanine, and tyrosine and the catecholamines 3-(3,4-dihydroxyphenyl)alanine and 3-(3,4-dihydroxyphenyl)-2-methylalanine at different pH levels. A significant difference...
متن کاملRibonucleic Acids: Capillary Electrophoresis
With the introduction of capillary electrophoresis (CE), a new generation of electrophoretic techniques has seen the light of day. The scientiRc literature today describes a large number of applications of this powerful analytical technique in the analysis of nucleic acids. For nucleic acids, as for most other analytes, CE offers signiRcant advantages over many of the conventional electrophoret...

متن کاملDetermination of organic acids of low molecular weight and phosphate in soil by capillary electrophoresis.
Capillary zone electrophoresis with indirect UV detection at 254 nm was found to be suitable for the determination of organic acids and phosphate in aqueous extracts of soil. The best support electrolyte solution was found to be 10 mM p-hydroxybenzoic acid with 0.5 mM tetradecyltrimethylammonium bromide to reverse electroosmotic flow. This methodology was tested with 9 analytes found in soils: ...
