Microcalorimetry uses a suite of techniques to directly measure enthalpy and heat capacity changes that arise when chemical reactions occur. In aqueous solutions, heat flux into or out of the sample almost always happens on reaction. These reactions may involve a wide variety of situations, e.g., the interaction of two molecules (such as a cyclodextrin and its guest), changes in the conformation of complex macromolecules (such as proteins or DNA), or even in the structure of very complex multimolecular colloidal drug delivery systems (such as liposomes).
Microcalorimetry (- 40°C to 200°C) Highlights include: – The microSC microcalorimetry instrument performs at a wide temperature range covering -40 to 200°C – 2 measuring cells, featuring zero cross talk, and easily removable and reusable cells – High precision isothermal and scanning options are available to enable the study of both transitions and long term isothermal […]
High-sensitivity DSC and microcalorimetry (-45 to 120°C) The HIGHLIGHTS • Wide operating temperature range (from -45 °C to 120 °C): cooling of the calorimeter does not require an external source. • Use in isothermal or temperature programming (DSC) mode. • Possibility to study samples in all forms: liquids, gel, powder, solid. • Variety of closed […]
