A new thermostat/cryostat technique for conventional and temperature-modulated differential scanning calorimetry

We present a new top-loading vacuum insulated thermostat/cryostat for temperature-modulated differential scanning calorimetry (TMDSC) and DSC measurements covering an outstanding temperature range.

Description
Summary:We present a new top-loading vacuum insulated thermostat/cryostat for temperature-modulated differential scanning calorimetry (TMDSC) and DSC measurements covering an outstanding temperature range. TMDSC measurements are now possible down to 60 K. As a consequence of its construction features, contamination by moisture is completely eliminated. In particular, the important time domain technique can be applied without any time limit, thus allowing precise C sub p measurements even in the immediate vicinity of phase transitions. Experimental results are presented to show the performance of the modified TMDSC system. (Example materials include strontium titanate, polyvinyl acetate, and a fluoropolymer.)
