Description
technical field [0001] The invention relates to the technical field of solution concentration analysis equipment, in particular to an experimental pretreatment color image capture comparison analysis system. Background technique [0002] There are many products that need to be pretreated before the chemical analysis process. At this time, many chemical reagent solutions with different concentrations will be used. How to accurately determine the concentration of the chemical reagent solution used has always been a technical issue that those skilled in the art are very concerned about. [0003] There are many methods for measuring solution concentration in the prior art, but generally the solution is firstly diluted, and then different methods are selected according to the characteristics of the solution, such as spectrophotometry, acid-base reaction method, reaction chromogenic method, etc. However, These testing methods in the prior art all have certain shortcoming. For exa...
