Microchip electrophoretic method and apparatus

摘要

In order to irradiate a constant range of a separation passage(55) of a microchip(5), light from a light source(1) linearly extending along the separation passage(55) is transmitted through cylindrical lenses(2, 4) and a bandpass filter(3) and introduced into the separation passage(55). The light transmitted through the separation passage(55) of the microchip (5) is introduced into a photocell array (7) through a cylindrical lens (6) and detected. Measurement is repetitively performed and accumulated to determine migration patterns. <IMAGE>
