The Perkin-Elmer 1020 series thermal analysis system

The performance of a Perkin-Elmer 1020 Series DSC7 Thermal Analyser has been tested between 20 and 700°C with respect to isothermal and dynamic baseline stabilities, sample and instrumental time constants, thermal resistances, and measurement of temperatures, heats and heat capacities. The system includes software which meets the demands of industry, but is unsatisfactory for research. The arrangement of the thermoelectric coolers enables thermal equilibrium to be achieved in a short time, minimizes the isothermal drift, and makes it possible to start programming from subambient temperatures.
