SPECTROPHOTOMETER-ANALYZER Russian patent published in 2001 - IPC

FIELD: spectroscopy of substances. SUBSTANCE: proposed spectrophotometer-analyzer is related to automated facilities for information collection and processing, specifically, to automatic proximity analyzers of compositions of substances used in geology and environmental control. It incorporates laser with power supply unit, focusing optical systems, prism, photodetector, pulse generator, two flip-flops, shift register, pulse former, solitary AND gates, groups of AND gates, storage of codes of elements, register of on- line storage, comparator incorporating AND, NOT, NAND gates, pulse distributor, step electric motor and unit recording results o analysis. Spectrophotometer-analyzer takes down names of chemical elements detected in analyzed substance and keeps them in unit recording results of analysis ensuring high-speed operation and excluding subjectivism in results of analysis. EFFECT: enhanced speed of collection and processing of information on analyzed substances, exclusion of subjectivism in results of analysis, increased authenticity of results of analysis. 1 cl, 3 dwg
