Abstract
An improved differential thermal analysis/differential scanning calorimetry (collectively, DSC) assembly with a furnace block assembly having a measurement chamber and a furnace heater. The measurement chamber has a sensor assembly for receiving a sample material and a reference material. The furnace block assembly is coupled to a generally cylindrical cooling flange through a distributed thermal resistor that allows a constrained heat flow between the furnace assembly and cooling flange. The thermal resistor can also withstand the mechanical stresses associated with the differential expansion and contraction of the furnace assembly and cooling flange without permanent deformation of the thermal resistor. The cooling flange can be coupled to various cooling devices, permitting operation of the overall DSC instrument in a variety of temperature regimes for a variety of applications.
