Abstract: A capillary calorimetric cell comprises a solid metallic block having a plurality of channels formed therein. Each channel has first and second ends opening to a first end face and a second end face, respectively, of the block. First and second members are disposed at the first and second end faces of the block, respectively, and cooperate with the block so that adjacent first ends and adjacent second ends of the channels are connected to thus form a single, continuous channel through the block.

Abstract: A method for measuring the heat of reaction resulting from the mixture of a plurality of reagents comprising the steps of providing a first reagent into a compartment; providing a second reagent into the compartment so as to mix the second reagent with the first reagent within the compartment; withdrawing a predetermined amount of the mixed first and second reagents from the compartment; depositing the withdrawn predetermined amount of the mixed first and second reagents back into the compartment; generating electrical signals based on the heat of reaction of the mixed first and second reagents; and deriving data indicative of the heat of reaction based on the electrical signals.

Abstract: A differential scanning microcalorimeter comprises an adiabatic shell accommodating two capillary calorimetric chambers. One end of each chamber extends beyond the shell and passes through a heat bypass. At least one chamber is contrived in the form of two capillary tubes in thermal contact with each other, with the ends located inside the shell communicating with an end of the other chamber also located inside the shell.
