A computer assisted heat capacity measuring system has been designed from commercial components. A differential scanning calorimeter of type Perkin-Elmer DSC-2 forms the basis for measurements from 100 to 1000 K. A Hewlett-Packard calculator (minicomputer) of type 9821 is the data handling system. The data are collected and permanently stored on teletape. The program has been written to govern measurement and final computation, tabulation, plotting, and curve fitting. Calibration is done by comparison with benzoic acid or aluminium oxide (sapphire). Zinc heat capacities have been measured as an example and for evaluation of accuracy. Accuracies of better than ± 0.5% have been achieved, an improvement of approximately a factor 3 to 5 over a similar system without computer assist. The system will be used mainly for heat capacities of linear macromolecules.
