Abstract

In a temperature-modulated differential scanning calorimetry (TMDSC) system, temperatures are measured by thermocouples under the sample and reference furnaces. TMDSC helps the researcher to establish a more realistic model to calculate heat capacity of various materials. This study examined the assumptions about temperature gradients in TMDSC characterization. An infrared camera was used to obtain surface temperature maps of DSC cells during temperature sweeps. TMDSC units from Perkin-Elmer and TA Instruments were studied using different heating and cooling rates. Temperature gradients exist between the top and bottom of the sample. IR images showed that temperature distributions within the sample and reference cells exist. Phase lags between the top and bottom temperatures were also observed.
