A cradle-glass ampoule sample container for differential scanning calorimetric analysis

A sample container system was developed, which consists of a sealed micro-ampoule as the sample pressure vessel and a special ampoule cradle designed to optimize heat detection efficiency, reproducibility, baseline stability, and thermal responses. The heat detection efficiency and thermal responses of the sample container system were determined and compared to those of others. The reproducibility of heat measurements has been assessed using several common thermal standards and other chemicals. The interpretation of heat measurements by differential scanning calorimetry is also discussed.
