Design and Development of Ultra-Sensitive Multi-Task Thermal Analyzer Applicable to Various Food Components

利用真空溅射法成功地制备了薄膜热电堆。然而，事实证明，它们具有很高的电阻，当它们被放置在具有曲率的材料表面时，很容易断裂。因此，必须放弃它们作为本研究项目中要开发的热分析仪的传感器。利用普通方法在显微镜下制备的微热堆，成功研制出高灵敏度的绝热DSC。同时，为了从观测到的DSC信号中推导出热力学参数，开发了一种算法，并构建了计算这些热力学参数的计算机软件。结果表明，所建立的体系可用于各种食品成分的定量表征。

Manufacturing of thin-film thermopiles was successfully done by means of vacuum-spattering method. However, it turned out that they have a high electric resistance and are easily broken when they are placed to fix on a material surface with curvature. For this reason, their employment as a sensor for the thermal analyzers to be developed in the present research project had to be given up. In return, micro-thermopiles prepared under the microscope by an ordinary method was employed and a high sensitive adiabatic DSC was successfully developed.At the same time, in order to derive the thermodynamic parameters from observed DSC signals, an algorithm was developed and the computer software for leading these thermodynamic parameters was constructed.It was concluded that the developed system can be applicable for the quantitative characterization of various food components.
