Developing a novel research method by assembling elements and equipment is a significant way of innovation in science and technology. Considering the assembly of DTA-Raman hyphenated system as an example, the modules available in a laboratory were assembled to form a differential thermal analysis (DTA) section. This section was designed to meet the practical conditions for Raman spectral measurement. The phase transition of mixed molten salts was investigated using this DTA-Raman spectroscopy hyphenated system. Through the construction and measuring process, students can understand the principle of DTA in detail and recognize the enhancement effect from the combined use of several experimental techniques. Furthermore, they will learn to establish a new research method from the available materials. Therefore, this experimental teaching case can effectively contribute to the improved creativity and scientific research ability of the students. Finally, this experiment can further improve the aspects of the DTA test platform, data acquisition unit, and phase diagram determination. Thus, sustainable innovation can be expected from this open experimental teaching project.
