The purpose of this study is to develop a multi-functional thermal analysis system to conduct simultaneous thermal and mass analysis of nano-gram level sample. Because the cantilever type chip calorimeter has low heat capacity, high heat resistance and highly integratable feature, it can conduct nano-gram level thermal analysis with high speed temperature scan and high sensitive thermal measurement. Furthermore, mass measurement by using mechanical resonance of the cantilever type chip-calorimeter is also possible. In this study, the DTA and thermal mass analysis of tiny copper sulfate pentahydrate were conducted with the calorimeter. In the DTA, two endothermic peaks corresponding to a mass reduction of 460ng were measured in heating phase of first temperature scan. Also, in the thermal mass analysis, stepwise mass reduction was observed through the differential analysis between heating and cooling phase data.
