摘要：

The performance of the Flash DSC 1, a recently introduced, commercial available chip fast scanning calorimeter (FSC) based on MEMS sensor technology, was studied. Topics included calibration; symmetry; repeatability; scan rate control windows of operation. Scan rates up to 20 000 degrees C/s for empty cell measurements in cooling and heating have been achieved. By combinations of scan rates up to 1000 degrees C/s various topics in between -95 to 450 degrees C were studied on polymers including self nucleation; annealing and thermal fractionation; 'hot' and 'cold' crystallization; amorphization; and cross-over of crystallization behavior with scan rate variation for two polymers. Sample masses around 1 mu g and less gave good results with excellent repeatability and acceptable thermal lags. The Flash DSC 1 enables to mimic realistic conditions of practice and to measure (meta)stability and reorganization phenomena of substances and materials, including polymers, metals, pharmaceuticals etc. (C) 2011 Elsevier B.V.
