Abstract

This paper introduces a new measuring method in Isothermal Titration Calorimetry (ITC). This method, based on a proportional-integral control system, offers many important advantages when compared to the frequently used proportional control: higher signal-to-noise ratio, improved stability of baseline, increased static and dynamic sensitivity, similar or smaller time constants and calibration constant independent of the control parameters.

Here an experimental proof of this method is detailed and full theoretical foundation will be discussed in a next paper.
