We show how to avoid common accuracy-limiting mistakes in isothermal titration calorimetry, and provide a simple spreadsheet to aid in propagating the dominant source of uncertainty (titrant concentration errors) into the resulting thermodynamic parameters.

Keywords: isothermal titration calorimetry; ITC; propagation of error; entropy-enthalpy compensation
