ABSTRACT
Simultaneously measured high-resolution enthalpy and heat capacity data are obtained by means ofa novel type Peltier-element-based adiabatic scanning calorimeter that can also operate as a classicaladiabatic heat-step calorimeter. Specific enthalpy and specific heat capacity results with 2% uncertaintyand sub-mK temperature resolution are presented for the melting transition of the calorimetric referencematerials biphenyl and phenyl salicylate. The simultaneously obtained enthalpy and heat capacity dataallow for a simplified and reliable purity analysis.
