Abstract:
A multi-capillary electrophoretic apparatus comprising:a multi-capillary array electrophoresis part having an arrangement of a plurality of capillary columns for injecting each of a plurality of samples into said capillary columns and simultaneously electrophoresing said samples in all said capillary columns; an optical measuring part for measuring scan waveforms by irradiating said capillary columns with light in said multi-capillary array electrophoresis part, scanning irradiated positions in a direction perpendicular to an electrophoresis direction, and detecting the intensity of light from said samples of irradiated parts; and a data processing part for producing time-series data as to each said capillary column from said scan waveforms obtained by said optical measuring part, wherein said data processing part comprises a saturated data correction part for correcting saturated peaks included in said scan waveforms to light intensity value measured on the assumption that said peaks are unsaturated, and produces said time-series data on the basis of unsaturated scan waveform peaks with no correction and light intensity value of saturated scan said data processing part further comprises a capillary position correction part for periodically correcting capillary column position information for data acquisition and acquiring said time-series data from said scan waveforms on the basis of corrected capillary column position information when producing said time-series data from said scan waveforms.
