Isothermal Microcalorimetry

Isothermal calorimeters (IC) measure the power change for time-dependent phase transitions or processes. Instruments that are designed to measure power on a micro-Watt scale are termed isothermal microcalorimeters. They can study solids, liquids or heterogeneous mixtures and the design of the reaction vessel is critical. In this chapter, the principles, experimental arrangement and application of isothermal calorimetry are discussed.
