Abstract:
1. A measuring chip for separating and measuring a target component in a sample by rotation around a first axis and a second axis of rotation, comprising: a centrifugal separation tube for centrifugally separating the target component from the sample by rotating the measuring chip around the first axis of rotation; a first holding section provided in the bottom of the centrifugal separation tube, wherein non-target components in the sample are introduced therein by rotation around the first axis of rotation, and the first holding section holding the non-target components during rotation around the second axis of rotation; and a plurality of measuring sections that measure the target component introduced from the centrifugal separation tube by rotation around the second axis of rotation; wherein a first measuring section of the plurality of measuring sections is connected with one end of the centrifugal separation tube, a measuring section after the first measuring section is connected to a preceding one of the measuring sections so as to introduce the target component into a following one of the measuring sections from the preceding one of the measuring sections, and the volume of the following measuring section is smaller than the volume of the preceding measuring section.
