Abstract
When a microchip is set on a tray and operation of an apparatus is begun, the microchip moves to feed position in order to be filled up with a buffer solution, where upon a sample is injected into this microchip. Thereafter the tray is located on a detecting position, so that a sample introduction voltage is applied between a sample reservoir and a sample waste reservoir for introducing the sample into a separation passage. Subsequently, the operation is switched to application of a separation voltage between a buffer reservoir and a drain reservoir, for beginning analysis. When the analysis has begun, a detector detects a migration pattern in the separation passage, so that a signal processing board data-processes the detected pattern.
