Stability can be studied using batch, scanning, and flow calorimetry. In
this example a compound was studied using gas flow microcalorimetry.
First argon was passed over the sample for 6 hours at 80 C to determine
thermal contributions other than oxidation.
The gas flow was switched to oxygen and a significant exotherm was
observed. Measurement of the heat flow after steady state conditions are
met, at different temperatures, makes it possible to determine the activation
