<p>When a microchip (10) is set on a tray (40) and operation of an apparatus is begun, the microchip (10) moves to feed position (C) in order to be filled up with a buffer solution, where upon a sample is injected into this microchip (10). Thereafter the tray (40) is located on detecting position (B), so that a sample introduction voltage is applied between sample reservoir (S) and sample waste reservoir (W) for introducing the sample into a separation passage. Subsequently, the operation is switched to application of a separation voltage between buffer reservoir (B) and drain reservoir (D), for beginning analysis. When the analysis has begun, a detector detects a migration pattern in the separation passage, so that a signal processing board (50) data-processes the detected pattern. <IMAGE></p> |
