Abstract
A channel () is formed inside a transparent substrate (), and the two ends are respectively connected to a sample inlet () and a separation medium filling port () both open to outside, and a sample outlet () which is open to outside is provided on the channel (). The portion between the sample inlet () and the sample outlet () is a separation channel portion (), and the portion between the sample outlet () and the separation medium filling port () is a separation medium introduction channel portion (). A separation medium supplier is connected to the separation medium filling port () and the separation medium introduction channel portion () is filled with a separation medium. Then a sample is dropped to the sample inlet (), with the sample medium supplier still connected, to introduce the sample to the separation channel portion (). And then, buffer liquid is poured in buffer reservoirs () and () and a migration voltage is applied to perform a migration analysis. Since an analysis can be repeatedly performed with the sample medium supplier kept connected, it is not necessary to disconnect the supplier from the electrophoretic chip each time a migration is performed.
