Patent ID: 7834998

Claim:
A biochemical analyzer, comprising: a kit for biochemical analysis that has a first substrate having a surface with a flat first plane and a second plane, the second plane having a vertical elevation compared to the first plane and a second substrate having a flat base, wherein the second plane of the first substrate is brought into contact with the base of the second substrate to assemble the kit, and a liquid specimen solution is introduced into a gap formed between the first plane of the first substrate and the base of the second substrate to make the kit ready to use, and probes immobilized on a site of the first plane of the first substrate and probes immobilized on a site of the base of the second substrate, respectively, are aligned so as to face each other across the gap after being assembled, each of the probes on the site of the first plane of the first substrate being the same kind as corresponding ones of the probes on the site of the base of the second substrate positioned to face the probes of the first substrate when assembled; a fixing section for fixing the cell for biochemical analysis; a light source; a spectrometer; an optical system for guiding light from the light source to a space below the first plane of the first substrate of the cell for biochemical analysis; an optical system for guiding reflected light from the cell for biochemical analysis to a spectrometer; and a computer unit for detecting a change in a reflection spectrum from an output of the spectrometer.
