Automatic Biochemical Analyzer Using A Spectrophotometer

Full-Auto-Bioanalyzer is a kind of typical Fine Instruments with Optic-Mechanic-Electric. The spectrophotometer is a crucial component. It's performance will affect the performance of entire system. An ultraviolet-visual spectrophotometer for Full-Auto-Bioanalyzer supported by "9. 5 Project" was reported in this paper .The spectrophotometer for bioanalyzer was designed with concave holographic aberration-reduced grating as spectroscope and photoelectron diode array as detector. Composite light, emitted by light source, is absorbed by sample resolution firstly, then illuminate to the surface of concave holographic aberration-reduced grating. Photoelectron diode array received 12 beams of light signal at the same time . This technology belongs to the technology of back-dividing-light that can realize fast measurement.This paper was divided into three sections: the basic composition of spectrophotometer, the theory of spectrophotometer, the designing of spectrophotometer for Full-Auto-Bioanalyzer.In the first section, Beer Law, which spectrophotometer analyzing chemic substance quantitatively and qualitatively depends on, was discussed firstly. Then the classification, structure, the every component of spectrophotometer was discussed . At last, the characteristic parameter of spectrophotometer and it's test method is discussed. The designing process of concave holographic aberration-reduced grating through the theory of aberration was introduced in the second section . The spectrophotometer system for Full-Auto-Bioanalyzer is dicussed in the third section . The examination results proved that the spectrophotometer designed in this paper meet the need of Full-Auto-Bioanalyzer , and can be used for bio-examination .
