WebDifferential scanning calorimeters offer temperature ranges as low as -180C and as high as 2400C, with the highest available heating rate at 300 K/min for DSC analysis. The principle models utilize heat flux systems, corrosion-free silver furnaces, or cylindrical high-conductivity silver block units, among others. WebAt this heating rate, the melting process is completely separated from the decomposition process. Conclusions. The Flash DSC 1 allows physical effects to be separated if the maximum possible heating rate of 2.4 million K/min is sufficient to shift a heating rate-dependent effect to such an extent that it no longer overlaps the second effect.
