Thermometric titration - the better method to determine total sodium in foodstuffs

摘要

In the case of thermometric titration, however, the sensor is a fast responding thermometer. Hence, instead of measuring the electrochemical potential in the solution, this robust, highly sensitive thermometer tracks the reaction enthalpy, i.e., the temperature change in the solution.The endpoint of the titration is marked precisely by the moment, when the reaction stops and no significant temperature change is registered any longer in the solution. Because it relies merely on a change of solution temperature to find the endpoint, there is no need to calibrate the sensor. Sensor maintenance is minimal, and it can be stored dry between titrations.
