Abstract
An object of the present invention is to provide a capillary electrophoresis apparatus in which simultaneity can be ensured between sensitivity and data acquisition to decrease a pull-up signal while spectral data acquisition is eliminated in each capillary exchange. The invention relates to a capillary electrophoresis apparatus characterized in that a multi-bandpass filter is provided in an optical detection system. In one aspect of the invention, a signal detection area of a two-dimensional detector is divided into plural regions corresponding to wavelength transmission regions of the multi-bandpass filter. An integrated value of the fluorescence spectrum signal is determined in the region including a fluorescence spectrum peak of an analysis sample in the plural regions. The analysis is performed with the integrated value.
