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 ...
متن کاملDetermination of propionate in bread electrophoresis using capillary zone
A method for the determination of propionate in bread is described. The propionate was extracted from the bread with a repeated extraction procedure and measured using capillary zone electrophoresis in the indirect UV mode applying a background electrolyte of 0.005 M Tris adjusted at pH 4.6 by adding benzoic acid. Using laboratory-baked bread containing known amounts of sodium propionate, recov...
متن کاملDetermination of carbohydrate-deficient transferrin using capillary zone electrophoresis.
BACKGROUND Current methods for carbohydrate-deficient transferrin (CDT) often suffer from low precision, complexity, or risk of false positives attributable to genetic variants. In this study, a new capillary zone electrophoresis (CZE) method for CDT was developed. METHODS CZE was performed on a P/ACE 5000 using fused-silica capillaries [50 microm (i.d.) x 47 cm] and the CEOFIX CDT buffer sys...
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: ...
