An analysis device includes a guide-in section, a piercing member, an airtight member, a gas introduction member, and a measurement member. The guide-in section is configured to guide a rectangular block shaped analysis kit containing a sample. The piercing member pierces a sealing film at an upper face of a liquid reservoir formed in the analysis kit. The airtight member forms an airtight space against the analysis kit at the periphery of a location pierced by the piercing member. The gas introduction member introduces gas into the airtight space. The measurement member measures a component present in the sample in the analysis kit guided into the guide-in section.

Analysis device

An analytical method and an analytical system capable of more accurate analysis, in which a sample is analyzed by a capillary electrophoresis technique in which a voltage is applied to a sample solution introduced to a micro flow path, a separation analysis is performed for a component contained in the sample solution, and an optically measured value corresponding to an elapsed time after starting a measurement is measured. The analytical method comprises: a process of determining an interface arrival time point, based on the optically measured value when an interface between the sample solution and a migration liquid reaches a predetermined measurement position in the micro flow path; and a process of identifying the component contained in the sample solution using the optically measured value at the elapsed time after the interface arrival time point.
