Optimum Condition for Accurate Heat Capacity Measurements in Temperature-Modulated Differential Scanning Calorimetry

PDF Version Also Available for Download.

Description

We explored the optimum conditions in modulation of the program temperature and sample preparation to obtain absolute values of heat capac- ity from quasi-isothermal measurements of temperature-modulated differen- tial scanning calorimetry. A Mettler-Toledo 820 calorimeter and Perkin-Elmer DSC 7 were used for this work, using saw-tooth modulation as well as sinu- soidal modulation. We adopted a simple model to analyze the temperature response of the calorimeters and calibrated the results more precisely.
