dc.description.abstract | We introduce a four-step technique for the accurate determination of the heat capacity of
volatile or air-sensitive samples using relaxation calorimetry. The samples are encapsulated in a
hermetically sealed differential scanning calorimetry pan, in which there is an internal layer of
Apiezon N grease to assist thermal relaxation. Using the Quantum Design physical property
measurement system to investigate benzoic acid and copper standards, we find that this method can
lead to heat capacity determinations accurate to +/- 2% over the temperature range of 1-300 K, even
for very small samples (e.g., < 10 mg and contributing ca. 20% to the total heat capacity). (c)
