Abstract

The reaction calorimeter CAP202 (chemical process analyzer) determines thermal effects by measuring the true heat flow (THF) based on unique design principles. In particular, measurements can be performed without requiring any calibration procedures and the obtained results are most reliable and exhibit extremely stable baselines. The benefits in respect of experimental speed, data quality and long term performance are obvious. Due its broad dynamic range the instrument can be employed for measurements ranging from small physical heat to energetic chemical reactions. The CPA allows running experiments seamlessly with reaction volumes between 10 and 180 mL. This volume flexibility simplifies the investigation of multi-step operations and is the basis for various applications employing precious or highly energetic compounds. Due to the fact that calibrations are not required, altering conditions during a single experiment like changes in viscosities, liquid levels or stirring speeds do not affect the results of the measurements.
