Abstract

The invention relates to the technical field of instruments and meters, in particular to a titrating device of a potentiometric titrator. The titrating device of the potentiometric titrator comprises a stirrer, wherein a tubular burette frame is vertically arranged on the stirrer; a jacket is jacketed on the tubular burette frame; a core is installed inside the jacket; an electromagnetic valve is inserted into the core; the electromagnetic valve is fixed by a branched screw; the titrating device of the potentiometric titrator further comprises a bent burette frame; the bent burette frame penetrates through the core; a burette is fixedly connected onto the upper part of the bent burette frame through a burette fixing screw; an electrode clamp is arranged at the lower part of the bent burette frame; a tightening ring is sleeved upon the lower part of the electrode clamp; a rubber pipe is arranged above the electromagnetic valve; the tail end of the burette is sleeved with the rubber pipe. The titrating device of the potentiometric titrator has the advantages as follows: the titrating device is simple in structure and greatly improves the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a titration device of a potentiometric titrator. Background technique [0002] Electrochemical analysis is a type of analytical method based on the measurement of the electrical response of a certain chemical system or sample. It constitutes the measured object as an integral part of a chemical battery. By measuring certain physical quantities of the battery, such as potential, current, conductance or electricity, etc., the content of the substance is obtained or certain chemical properties are determined. [0003] Potentiometric titration analysis method refers to using the indicator electrode, reference electrode, and test solution to form a working battery, titrate with a standard solution, record the change in the potential of the indicator electrode during the titration process, and use the characteristics of the sudden change in the potential of the indicator...
