Abstract

The invention discloses an intelligent chemical analysis system for distinguishing detection of a weak electrolyte sample and a method therefor. The intelligent chemical analysis system is characterized by comprising an embedded module, a potentiostat and a three-electrode sensor. The method comprises that the self-developed potentiostat combines with the embedded module; a two-step excitation acquisition method is adopted; through the first excitation acquisition process, solution resistance is automatically fitted and an electrical signal produced by the solution resistance is added to a secondary excitation signal; and through the combination of the second acquisition process, real-time Fourier transform and principal component analysis, an optimized weak electrolyte solution whole-distinguishing graph is obtained. The method has good detection effects, a wide application scope and low influence on solution properties.

Description

technical field [0001] The invention relates to an intelligent chemical analysis system and method for distinguishing and detecting weak electrolyte samples, which can provide an overall distinguishing diagram of weak electrolyte solution samples. Background technique [0002] Nowadays, electrochemical methods have been more and more used for the overall comprehensive evaluation of liquid samples, and great breakthroughs have been made in the identification of wine, tea drinks, fruit juice, and milk samples. [0003] The Chinese patent 200710068869X applied by the applicant of the present invention in 2007 discloses an intelligent chemical analysis system for liquid samples, which uses multi-frequency pulse voltammetry as the signal excitation acquisition mode, which has a stronger response signal and less signal noise than the prior art. The higher the ratio, the richer the amount of information. [0004] However, the electrochemical method also has certain defects, and th...
