Thermo titration

Thermometric Titration

Thermometric Titration is a very versatile titration method, because one sensor can be used for various kinds of applications, and it is exclusive to Metrohm. The temperature sensors (Thermoprobes) neithe 859 r are specific to any ion type nor does their performance depend on the electrochemical properties of the sample solution. They require virtually no maintenance and can be used immediately without any conditioning.

Therefore Thermometric Titration can solve applications problems, potentiometry cannot or at least not with satisfying reproducibility:

Each chemical reaction is associated with a change in enthalpy that causes a temperature change which, when plotted versus volume of titrant, can be used to monitor the course of the reaction and thus to detect the titration endpoint. For a simple reaction this means that the increase (exothermic reaction) or reduction (endothermic reaction) in temperature depends on the amount of substance converted.
