The design of the semi-automated biochemistry analyzer

The biochemistry analyzer has been widely used to quantitative measuring and analyzing various biologic and chemical elements of human body fluid in clinic. In this paper, a kind of semiautomated biochemistry analyzer based on C8051Fxxx single chip microcomputer is presented. The analyzer employed the photoelectric measurement method and the end-point analyzing method as well as dynamic analyzing method and so on. The measured items are above 40 and more than 1000 results can be stored. Moreover, the analyzer can communicate with the personal computer by RS-232 interface. Compared with the same type other product, this analyzer has the advantages of small volume, high ratio of performance to price and easy operation.
