Original Abstract

The paper provides information about the on-line monitoring of components analysed by capillary electrophoresis. For this purposes we developed a whole-capillary transverse scanning detection system, which helps to improve and control the separation processes. A picture from a colour line scanner was used as a source of basic information for autonomous control of the separation process by regulation of the high voltage source. The application and algorithms for machine vision were designed in the progressive graphic development system LabVIEW. Real-time control of the separation process was implemented in a compact control process logic controller. The performance of the detection system was evaluated and the function of the overall system was tested by performing isotachophoretic analysis of a model mixture.

článek přináší informace o on-line snímání složek analyzovaných kapilární elektroforézou. Pro tento účel jsme vyvinuli kapilární skenovací detekční systém, který napomáhá zlepšovat a řídit separační procesy. Snímek z barevného řádkového skeneru je zdrojem informací pro autonomní řízení separačního procesu pomocí regulace zdroje vysokého napětí. SW a algoritmy strojového vydění byly vytvořeny ve vývojovém prostředí LabVIEW. Real-time řízení separačního procesu bylo implementováno do kompaktního PLC. Chování detekčního systému bylo ověřeno izotachoforetickou analýzou směsi látek.
