High Quality Content by WIKIPEDIA articles! The method of sorption calorimetry is designed for studies of hydration of complex organic and biological materials. It has been applied for studies of surfactants, lipids, DNA, nanomaterials and other substances. A sorption calorimetric experiment is performed at isothermal regime, but different temperatures can be studied in separate experiments.In a sorption calorimetric experiment, a two-chamber calorimetric cell is incerted into a double-twin microcalorimeter. Water evaporates, diffuses through the tube connecting two chambers of the calorimetric cell and is absorbed by the studied substance.
