The principle of the upgraded titrator

The upgraded titrator adopts the principle of potentiometric titration to meet experimental needs:7taTextile Testing Instruments, Testing Equipment Manufacturer


The automatic potentiometric titrator can perform potentiometric titration, including acid-base titration and redox titration. Precipitation titration, complexometric titration and non-aqueous titration as well as constant pH measurement can also be performed. Optionally, titration analysis methods such as photometric titration, polarization titration, volumetric Karl Fischer titration and surfactant titration can be performed. 7taTextile Testing Instruments, Testing Equipment Manufacturer


When the automatic titrator is used online with the automatic multi-sample converter, it can not only efficiently realize the automatic measurement of a large number of samples, but also improve the repeatability and reliability of the analysis and the operation are easy and save time and effort. Applicable to quality control, Inspection, analysis, research, development and other aspects. 7taTextile Testing Instruments, Testing Equipment Manufacturer


Principle7taTextile Testing Instruments, Testing Equipment Manufacturer


Titrate the reagent solution (standard solution) of known exact concentration into the predicted substance solution from the burette until the reagent is added Content of the predicted substance is determined from the concentration and volume consumed until the predicted substance is quantitatively reflected stoichiometrically. 7taTextile Testing Instruments, Testing Equipment Manufacturer


Potentiometric titration7taTextile Testing Instruments, Testing Equipment Manufacturer


Potentiometric titration: A method of determining the end point of titration by measuring the change in potential during the titration process. There are also color changes to determine the endpoint, such as 7taTextile Testing Instruments, Testing Equipment Manufacturer


HOW IT WORKS7taTextile Testing Instruments, Testing Equipment Manufacturer


A method of determining an endpoint. 7taTextile Testing Instruments, Testing Equipment Manufacturer


The potentiometric titration method shows the end point of the titration by the sudden jump of the electrode potinitially on. 7taTextile Testing Instruments, Testing Equipment Manufacturer


Before and after the titration reaches the end point, the concentration of the ion to be measured in the droplet often changes continuously by n orders of magnitude, resulting in a sudden jump in potential The content of the measured component goes through consumption of the titrant. to calculate. 7taTextile Testing Instruments, Testing Equipment Manufacturer


In acid-base titration, the indicator electrode is used to show the change in hydrogen ion concentration in the solution into a change in potential to indicate the endpoint of the titration. 7taTextile Testing Instruments, Testing Equipment Manufacturer
