Full automatic titrimeter applied to volumetric method titration and working method thereof

Abstract

The invention relates to the field of experimental apparatus equipment, and discloses a full automatic titrimeter applied to volumetric method titration and a working method thereof. Via the creationof the invention, provided is a novel full automatic titrimeter that can completely simulate artificial operating steps according to a national standard method, namely that, via the specific structurearrangement of a first lifting mechanism, a titration work station, a pump mounting rack, a control panel mounting rack and a titration mechanism installation plate and auxiliary devices thereof, anupper computer can automatically perform whole-journey monitoring and titration operation control on a titration process, and achieves the purpose of automatically designing and simplifying the operation of staffs; the upper computer also can use a color recognition module arranged on the titration mechanism installation plate to replace human eyes to accurately acquire a color recognition resultof a reagent to be tested, exclude unnecessary interference and artificial deviation, and accord with national standard; and the upper computer can further accurately judge a titration end point according to a color recognition result to acquire a stable detection result.

Description

technical field [0001] The invention belongs to the field of experimental instruments and equipment, and in particular relates to a full-automatic titrator for volumetric titration and a working method thereof. Background technique [0002] Volumetric titration is an important method for detecting the content of specific components in a solution based on the change in the color of the titration solution to determine the end point of the titration. It is not only a means of quantitative analysis, but also a chemical experiment operation. Determine the amount of a certain solute. There are two methods for judging the end point of volumetric titration: (1) determine the titration end point according to the color change in the titration process by artificial naked eyes, that is, indicate the titration end point according to the color change of the indicator, and then visually measure the consumption volume of the standard solution, Calculate and analyze the results; (2) use the...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the existing volumetric titration process that the titration end point is easy to vary from person to person, there is discrimination deviation, the manual operation is heavy, and the automatic integration that cannot meet the national standard is impossible. The purpose of the present invention is to provide a method that can Fully automatic titrator for volumetric titration with method completely simulating manual operation steps and working method thereof
