A method for analyzing a sample using capillary electrophoresis is provided. By the method, following steps are performed. First, an original sample and an anionic group-containing compound are fixed to form a mixed sample, where the original sample contains an analysis component to be analyzed and a sub component other than the analysis component. Then, an aggregate of the sub component and the anionic group-containing compound is removed from the mixed sample. Then, electrophoresis is performed in a capillary tube with respect to a complex in which the analysis component and the anionic group-containing compound are bound to each other, while the mixed sample is continuously supplied.


Provided is a method for measuring the concentration of a substance in a blood sample, the method comprising the steps of: supplying the blood sample to a biosensor comprising a hematocrit electrode for measuring a hematocrit value on the surface of which electrode an electrically conductive polymer is coated by physical adsorption in the absence of a crosslinking agent; and calculating the concentration of the substance from the measured value of a first current resulting from application of a first voltage; and correcting the concentration of the substance with the value of a second current resulting from application of a second voltage or the hematocrit value calculated from the value of the second current.

A cell culture device comprising:a channel having an inlet end for the introduction of a liquid and a bottom surface, wherein said channel is configured for the flow through of said liquid; anda plurality of recesses for containing cells, which are formed on said bottom surface of said channel;wherein said plurality of recesses are closely arranged on said bottom surface of said channel.


A sensor insertion method for inserting a sensor into a users body is provided. The method includes a unit fixing step of regulating a relative position between a sensor control unit and an inserting unit, where the sensor control unit is in a sensor insertion allowing state, and the inserting unit contains the sensor. In this step, the sensor control unit and the inserting unit are fixed to an insertion target portion of the user. Then, in a sensor inserting step, the inserting unit is caused to insert the sensor into the insertion target portion. In a sensor connecting step, the sensor control unit is shifted from the sensor insertion allowing state to a sensor connecting state, whereby electrical conduction is established between the sensor in the insertion target portion and the sensor control unit.
