Direct Observation of Capillary Electrophoretic Phenomena Using Video Image Analysis System

A video imaging system was developed for direct observation of the seperated zones of DNS-amino acids inside a capillary during an electrophoretic run. Using a CCD video camera, the moving zone of fluorescent band was observed after irradiation of capillary with a UV lamp and monitored in 10 cm region of a capilliary. On-line data acquisition in addition with the possibility of further image processing, made it possible to get a clear and real image of the seperated bands of solute.
