Focusing effects in multidimensional liquid-phase separations
Provider: Grantová agentura ČR
Programme: Standardní projekty
Implementation period: 01.01.18 - 31.12.20
Workplace:
Fakulta chemicko-technologická - Katedra analytické chemie
Investigator: Česla Petr
Description:
New two-dimensional liquid chromatographic methods will be developed in online configuration with active focusing of the zones of transferred fractions with electrodriven principles. The possibilities of improvement of sensitivity of two-dimensional chromatography using fraction trapping columns will be tested. The effects of experimental setup, conductivity, pH, application of micellization and complex-forming additives on the efficiency of focusing of transferred zones will be evaluated. The two-dimensional separation methods combining principles of electromigration separations in the first dimension with liquid chromatography in the second dimension will be developed. New methods will be applied in the analysis of plant extracts, food samples and analysis of industrial samples of complex mixtures.
