A sample-saving method for heat capacity measurements on powders using relaxation calorimetry

► A method for low-temperature heat capacity measurements on powders is presented. ► The method is based on combined PPMS and DSC measurements. ► It allows entropy determinations on powders with an accuracy of better than 1%. ► The sample is not mixed with Apiezon N grease during measurement. ► This is useful for samples that are only available in tiny amounts.
