VOLTAMPEROMETRIC ANALYZER Russian patent published in 2000 - IPC

FIELD: analytical chemistry, analysis of solutions by methods of voltamperometry. SUBSTANCE: it is suggested that voltamperometric analyzer should be supplemented with compensator made of second analog adder and source of compensating voltage and controlled amplifier. Processing unit should be added with microelectronic computer, generator of phase sequences, interface module and on-line storage of programs. Module communicating with peripheral devices of processing unit should be provided with additional port of sequential reception of data. Source of constant and linearly changing voltage is to be added with third digital-to-analog converter, controlled integrator and third analog adder. Technical objective of invention lies in provision of capability to conduct electrochemical analysis by various methods of voltamperometry, of flexible change of algorithms of analysis, of simultaneous determination of various substances in multicomponent solution with required precision in wide range of mutual relation of analytical signals of determined substances. EFFECT: expanded functional capabilities of analyzer. 6 dwg
