Fast flash DSC chip calorimetry
Quantum leap in innovation opens up new frontiers in material science
Differential scanning calorimetry (DSC) is the most important method in thermal analysis. It measures the heat flow to or from a sample as a function of temperature or time and thereby allows physical transitions and chemical reactions to be quantitatively determined. The Flash DSC revolutionizes rapid-scanning DSC. The instrument can analyze reorganization processes that were previously impossible to measure in a temperature range from -95 to 1,000 °C.
In contrast to conventional DSC, samples are placed directly onto the MultiSTAR™ chip sensor in the Flash DSC, such that effects caused by the crucible material are eliminated. In addition, the patented dynamic power compensation control circuit allows measurements to be performed at high heating and cooling rates with minimum noise levels.
Polymers, polymorphic substances, many composites and blends have metastable structures that depend on the cooling conditions used in their production. On heating, reorganization processes such as the melting and recrystallization of unstable crystallites or the separation of phases may occur.
The influence of reorganization on the heating curve can be analyzed by varying the heating rate.
Flash DSC can simulate technical processes in which rapid cooling occurs. This yields information about the effect of additives (e.g. nucleating agents) under near-process conditions. Isothermal measurements provide information on the kinetics of transitions and reactions that take place in a few seconds.
