Air-leakage and checking method of thermal analysis instrument

Zhang Fei(College of Chemistry and Molecular Engineering,Peking University,Beijing 100871,China)  
The air tightness of a thermal analysis instrument is an important but usually ignored factor that influences remarkably the reliability and objectivity of the results.By virtue of the characteristic and difference in the DTA and TGA curves of calcium oxalate and graphite in pure nitrogen,air,and nitrogen containing various concentrations of oxygen,a facile and efficient checking method based on calcium oxalate thermal decomposition for Simultaneous DTA-TGA and Differential Thermal Analyzer and another method based on graphite thermal decomposition for Thermogravimetric Analyzer are proposed.
