Description

Automatic titration device capable of preventing shaking and sprinkling

Technical Field

The utility model relates to an automatic titration technical field specifically is a can anti-shake unrestrained auto-titration device.

Background

The existing automatic potentiometric titrator can perform constant pH measurement besides potentiometric titration methods including acid-base titration, redox titration, precipitation titration, complexometric titration and non-aqueous titration. By selecting the components, photometric titration, polarization titration, volumetric method Karschner's water titration and surfactant titration, and equal titration analysis methods can be carried out. When the automatic titrator is used with the full-automatic multi-sample converter on line, the automatic titrator not only can efficiently realize the automatic measurement of a large number of samples, but also can improve the repeatability and reliability of analysis, and is simple to operate, time-saving and labor-saving. The method is suitable for various aspects such as quality control, inspection, analysis, research, development and the like. The automatic titrator is a laboratory titrator with high analysis precision, has perfect and powerful functions, and can be applied to the fields of food, drug inspection, disease control, inspection, commodity inspection, water treatment, petroleum, chemical engineering, oceans, electric power, environmental protection, new energy, teaching, scientific research and the like. The apparatus is modular and consists of volumetric titration device, controller and measurer. The apparatus has the functions of pre-titration, preset end point titration, blank titration, manual titration and the like, and can automatically generate a special titration mode, thereby enlarging the application range of the apparatus. A reagent solution (i.e., a standard solution) having a known accurate concentration is titrated from a burette into a solution of the predicted substance until the added reagent and the predicted substance are quantitatively reflected stoichiometrically, and the content of the predicted substance is determined from the concentration and the consumed volume. Potentiometric titration is a method of determining the end point of titration by measuring the change in potential during the titration. Also, the endpoint is determined by a color change, such as a color change of an indicator, a substance, etc. The experimental process is to measure the ion concentration by measuring the potential change of the electrode. In principle, 1. make up the working cell: and selecting proper indicating electrode and reference electrode to form a working battery together with the tested solution. 2. Adding a titrant for reaction: in the titration process, the concentration of the detected ions is changed continuously due to the chemical reaction, so that the potential of the indicating electrode is changed along with the change. 3. Ion mutation, potential jump, endpoint determination: in the vicinity of the titration end point, the concentration of the ion to be measured abruptly changes to cause a sudden electrode potential jump, and therefore the titration end point can be determined from the electrode potential jump and the measurement result can be given. However, the automatic titration apparatus in the market generally has the defect of easy shaking and spilling, so that the overall use feeling is influenced.
