AUTOMATIC ANALYSIS DEVICE

摘要

This analysis device is provided with a flow chamber in which a fluid including magnetic particles to which a labeling substance is bonded flows from a fluid inlet to a fluid outlet, a magnetic trap means for applying a magnetic field for trapping the magnetic particles in the fluid introduced into the flow chamber, a working electrode and a counter electrode for applying a voltage to the magnetic particles trapped by the magnetic trap means and causing light to be emitted, a photodetection element for detecting emitted light from the labeling substance on the magnetic particles trapped in the flow chamber, and a restricting means for restricting the region in which the photodetection element detects emitted light so that the emitted light from the labeling substance on a portion of the magnetic particles among the magnetic particles trapped by the magnetic trap means is detected.
