Biochemical analysis method and apparatus
View Patent ↗Samples and dry chemical analysis elements, which are necessary for analyses of the samples, are loaded on a sample tray. Each sample is sucked with a spotting nozzle of a spotting unit and spotted onto one dry chemical analysis element. Analysis information, which contains information representing a type of analysis, is appended to each dry chemical analysis element. The analysis information is read with a reading device located such that, when a certain sample is located at a position for sample suction by an operation of the sample tray, the reading device reads the analysis information, which has been appended to a next dry chemical analysis element to be used for the analysis of the certain sample, at a position at which the next dry chemical analysis element is located.
1. A dry chemical analysis element for biochemical analysis, comprising: i) a mount section, and ii) an analyzing region, which is to be spotted with a sample, the analyzing region being supported on the mount section, wherein analysis type information, production lot information, and advance direction information have been recorded on a surface of the mount section and with a dot recording technique for recording information by a dot array pattern, wherein the advance direction information is recorded by the absence of notation at a dot located at a specific site in the dot array pattern.
2. A dry chemical analysis element for biochemical analysis as defined in claim 1 wherein the dot array pattern is recorded at a position other than positions which overlap upon a bar code recording region having already been formed on the mount section, and both the dot array pattern and a bar code are capable of being recorded on the dry chemical analysis element.
3. A dry chemical analysis element for biochemical analysis as defined in claim 1 wherein the dot array pattern is recorded by use of a plurality of colors.
