Using of capillary isotachophoresis and on-line capillary zone electrophoresis for the determination of microcomponents in samples with complex matrices
Herrmannová, Michaela ; Křivánková, Ludmila ; Vytřas, K.
Beginning of capillary isotachophoresis is in seventieth years last century. Theory of the isotachophoretic separation process has been elaborated during twentieth years, the instrumentations were developed and considerable number of applications were publicated in articles. ITP-CZE enables in the first step to inject a relatively large sample volume, to separate sample components and to remove undesirable components. In the second step a simplified and defined part of the sample is analysed. Real samples of sweeteners, human serum and urine were analysed.
Principles of capillary zone electrophoresis and isotachophoresis
Křivánková, Ludmila
The principles of capillary zone electrphoresis and isotachophoresis, their instrumentation and on-line connection are described, and the possibilities of choice of background, resp. leading and terminating electrolyte are discussed.
Izotachoforetické stanovení umělých sladidel v modelovém vzorku
Herrmannová, M. ; Křivánková, Ludmila ; Vytřas, K.
An isotachophoretic method was elaborated that enables determination of sweeteners in a model sample containing eight sweeteners. The method is fast, cheap and reliable.
Determination of ethylglucuronide, the main metabolite of ethanol, in human serum by ITP-CZE
Herrmannová, M. ; Křivánková, Ludmila
It is possible to detect alcohol in human body only in a relatively short time after ethanol consumption. Ethylglucuronide as an alcohol metabolite, can be determined in body fluids, tissues and hair even after several days. ITP-CZE enables in the first step to inject a relatively large sample volume, to separate sample components and to remove undesirable components. In the second step a simplified and defined part of the sample is analysed
Trace analysis of iodide in biological and environmental samples by on-line combination of cITP-CZE
Urbánek, Marek ; Pantůčková, Pavla ; Křivánková, Ludmila
Development and application of the method of on-line combination of capillary isotachophoresis with capillary zone electrophoresis (cITP-CZE) for the determination of iodide in urine, seawater and in selected mineral waters.
Impact of sample matrix on quantitation in CZE
Gebauer, Petr ; Křivánková, Ludmila ; Pantůčková, Pavla ; Boček, Petr
Correct conditions for quantification based on peak height evaluation when UV detection is used were defined enabling to reach as high sensitivity as possible.
