Abstract: When detecting fluorescence of a bead chip array, reflected light from a bead is detected at the same time, so as to recognize the bead position. The reflected light can be detected in a similar manner for all beads, regardless of the presence or absence of a fluorescent substance. If the positions of all beads are detected, accurate detection can be achieved by quantifying only the fluorescence at the detected positions. The fluorescence wavelength alone is detected by a first detector using a wavelength selection filter. Other wavelengths are detected by a second detector, thereby obtaining the reflected light. Data on the reflected light is processed into an image for obtaining the bead profile, the bead position is recognized by detecting the center position based on the profile, and the fluorescence is quantified based on the bead position.

Abstract: There is provided an inspection chip capable of performing a number of solution feeding processes promptly and accurately. The inspection chip has one continuous flow path comprising a reaction flow path for accommodating a plurality of beads with immobilized probes of types different each other, a first and second solution holding flow path for holding a plurality of solutions each separated by an air gap. The solution is moved from one solution holding flow path to other solution holding flow path via a reaction flow path by utilizing pressure difference.

Abstract: A test chip, which allows a number of solution delivery steps much faster and accurate is provided. The test chip incorporates a sample flow path for containing a sample solution, a reaction flow path for inducing a predetermined reaction with the sample solution, a waste drain path for receiving the used sample, and the washing solution flow paths for containing washing solutions. The reaction flow path contains a plurality of beads having probes of mutually different types fixed thereon. The sample flow path, washing solution flow paths, and sample waste drain path have their respective solution detector units. The solution detector unit detects whether the solution is fed to the path. The detector units adjoiningly provided in the adjacent paths are arranged collinearly.
