Abstract: A sapphire interface with a closed cycle cryogenic cooler replace liquid nitrogen in cryotraps for gas chromatographs, cryofocusers for gas chromatographs, DMA's and DSC's. Inverse thermal properties of sapphire allow the closed cycle cooler to function at cryogenic temperatures at one end of a sapphire element while temperature of a test element is raised at the other end.

Substantial mass of the sapphire interface is eliminated by making the test element an integral part of the assembly and enables use of a smaller capacity cooling system. Low mass provides rapid temperature changes when switching between heating and cooling. The cooling requirement remains substantially constant, whether a test sample is heated or cooled.
