Abstract
The present invention is a mechanical cooling system, for use with thermal analysis instruments such as differential scanning calorimeters, which interposes a gaseous heat transfer path between the heat exchanger or evaporator cooling the differential scanning calorimeter cell and the differential scanning calorimeter cell. This configuration improves the performance of the thermal analysis system by reducing noise in the heat flow signal otherwise resulting from evaporation of the refrigerant in the heat exchanger. The mechanical cooling system is attached to the thermal analysis instrument by an arrangement providing for minimum direct physical contact between the mechanical cooling system and the thermal analysis instrument.
