    Simultaneous contactless conductivity detection and UV detection for the study of separation of tamsulosin enantiomers in discontinuous electrolyte systems by CE

  • Original language description

    This work shows the potential of using discontinuous electrolyte systems for the separation of tamsulosin enantiomers by CE. Sulfated beta-cyclodextrin was used as a chiral selector. In acidic electrolytes, sulfated P-cyclodextrin migrates as an anion and the analyte (tamsulosin) migrates as a cation. Due to this, four experimental arrangements were proposed. These arrangements differ in composition of electrolytes in the inlet compartment, in the capillary and in the outlet compartment. The separationof tamsulosin enantiomers in acetate buffers with sodium and Tris counterions was studied. Simultaneous contactless conductivity detection and UV detection were used for the study of the separation mechanism in these systems. Mobilities of sulfated beta-cycloclextrin were used for the calculation of the time when the analyte migrates through the BGE zone with the selector. The simulation program Simul 4.0 was used for the calculations of the concentration profiles of the electrolyte comp

    Simultanní bezkontaktní vodivostní a UV detekce pro studium separace enantiomerů tamsulosinu v diskontinuálním elektrolytovém systému CZE

  • Czech description

    Tato práce ukazuje možnosti použití dikontinuálních elektrolytových systémů pro separaci enantiomerů tamsulosinu pomocí kapilární elektroforézy (CZE). Sulfatovaný beta-cyklodextrin byl popužit jako chirální selektro. Byly navrženy 4 experimentální uspořádání, která se liší ve složení elektrolytů v inletu v kapiláře a outletu. Byla studována separace enantiomerů tamsulosinu v acetátových pufrech s Na a Tris protionty. Uvedené detekční systémy byly použity pro studium separačních mechanismů v několika systémech. Mobility sulfatovaných beta-cyklodextrínů byly použity pro výpočet času, kdy analyt migruje skrz BGE zónu spolu se selektorem.
