Nowadays various temperature control modes are used in thermal analysis; i.e., isothermal run, constant rate heating and cooling, sample-controlled thermal analysis, temperature jump, rate jump, temperature modulation, repeated temperature scanning, simulation for process development and temperature control for sample thermal history. Their advantages and drawbacks are reviewed with some illustrative examples, especially for application to kinetic analysis. The combined use of these modes is recommended to elucidate whole thermal behavior. Effect of heat transfer on the observed results is discussed for temperature modulation, repeated temperature scanning and jumps, and possibility of the imaginary part of the overall reaction rate constant in complex reactions is postulated, which is thought to appear in these modes together with the heat transfer effect.
