抄録

A laser-induced fluorescence detection system coupled with a highly sensitive silicon intensified target (SIT) video camera has been successfully applied to the imaging of a band for DNA fragment labeled with fluorescence dye and the visualizing of a separation process in the microchannel fabricated on a chip. We demonstrated that the imaging of the sample injection process is a powerful method for optimizing the electric potentials. Moreover, in microfabricated capillary electrophoresis (μ-CE) devices, continuous observation of the sample separation process is available. This direct imaging method is useful for the study of separation dynamics on μ-CE devices.
