Optimization of solid-phase extraction using artificial neural networks in combination with experimental design for determination of resveratrol by capillary zone electrophoresis in wines

Autor: Jiří Pazourek, Marta Farková, Josef Havel, Miroslava Spanilá

Publikováno v: Journal of Chromatography A. 1084:180-185

Solid-phase extraction (SPE) is often used for preconcentration of analytes from biological samples. Such an analytical step requires optimization for obtaining reliable results. Optimization in analytical chemistry is traditionally still often done

Analysis of polyphenols in wines: Correlation between total polyphenolic content and antioxidant potential from photometric measurements

Autor: Dagmar Gajdošová, Marta Farková, Klára Novotná, Miroslava Spanilá, Jiří Pazourek, Josef Havel

Publikováno v: Journal of Chromatography A. 1081:48-54

The polyphenols (some of them are also called phytoalexins, flavonols, flavanons, flavanonols, flavons, flavanols, and anthocyanines) are usually marked as potent antioxidants or radical scavengers which assist the body cells against oxidation. Polyp

Electroosmotic flow changes due to interactions of background electrolyte counter-ions with polyethyleneimine coating in capillary zone electrophoresis of proteins

Autor: Jiří Pazourek, Miroslava Spanilá, Josef Havel

Publikováno v: Journal of separation science. 29(14)

The properties and behavior of polyethyleneimine (PEI) covalently coated capillaries with respect to different background electrolytes used in capillary zone electrophoresis (CZE) are described. The coating stability and changes of inner surface char

Minimization of adsorption in capillary zone electrophoresis of proteins and neuroprotective peptides

Autor: Dagmar Gajdošová, Josef Havel, Jiří Pazourek, Ondřej Šulák, Miroslava Spanilá

Publikováno v: Collection Symposium Series.

Four types of coating procedures suitable for protein and peptides separation: covalent coating using polyethyleneimine (PEI), 3-glycidoxy-propyltrimethoxysilane (GPTMS), 3-aminopropyltriethoxysilane (APS) and a new approach of dynamic coating with l
