CHIP USING METHOD AND TEST CHIP

摘要

An object of this invention is to provide a test chip which allows efficient and convenient separation and weighing. This invention provides a weighing chip for separating and weighing a subject component of a sample by its rotation around first and second rotary shafts. The weighing chip comprises a centrifugal separation tube for centrifugally separating the subject component from the sample by rotating the weighing chip around the axis of the first rotary shaft, a first holding section installed in the bottom of the centrifugal separation tube wherein components (herein after referred to as non-subject components) other than the subject component in the sample are introduced thereinto by rotation around the axis of the first rotary shaft, and the first holding section holds the non-subject components in the rotation around the axis of the second rotary shaft, and a weighing section connected to one end of the centrifugal separation tube for weighing the non-subject components introduced from the centrifugal separation tube by rotation around the axis of the second rotary shaft.
