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

采用真空溅射法成功地制备了薄膜热电堆。然而，事实证明，它们具有高电阻，并且当它们被放置以固定在具有曲率的材料表面上时容易断裂。由于这个原因，他们的就业作为一个传感器的热分析仪在本研究项目中开发不得不放弃。同时，为了从DSC信号中提取热力学参数，开发了一种算法，并编制了计算这些热力学参数的计算机软件，结果表明，所开发的系统可用于定量表征各种食品成分。

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.
