Thin Film Thermocouples for Differential Thermal Analysis
Thin film thermocouples supported on quartz were developed for differential thermal analyses (DTA) over the range −125°C to 500°C. The low mass of the thermocouples, the small sample size, together with other design features practically eliminates problems from changes in heat transfer coefficient between sample and sensor. This results in very flat baselines and high precision measurement. It is this high degree of repeatability that distinguishes this DTA system from others. The system allows calorimetric values to be obtained from peak areas. Calibrations based only on indium yielded calorimettric data which agree well with the established literature.
