Abstract: A calorimeter comprises a sample cell 104 and a reference cell 102 with a heat sink that includes a diffusion-bonded block 200 that has higher thermal conductivity laterally across the block than through the block. The diffusion-bonded block has multiple metallic layers that are diffusion-bonded together, with relatively higher thermal conductivity layers alternating with relatively lower thermal conductivity layers. The diffusion-bonded block may be used in differential scanning calorimeters, multi-cell differential scanning calorimeters, nano-differential scanning calorimeters and isothermal titration calorimeters, as well as other calorimeters that measure differential heat flow to and/or from a sample with respect to the heat flow to and/or from a reference.
