Heats of Mixing Using an Isothermal Titration Calorimeter: Associated Thermal Effects
The correct determination of the energy generated or absorbed in the sample cell of an Isothermal Titration Calorimeter (ITC) requires a thorough analysis of the calorimetric signal. This means the identification and quantification of any thermal effect inherent to the working method. In this work,...
