We introduce a glass capillary crucible for DSC measurement that can be sealed by heating using an air-gas burner with cooling in an ice–water bath. The effect of the heating on the sample is minimal according to microscope photographs, DSC measurements, and thermal transport calculations. The sealing operation does not cause significant distortion of the glass of the sealed crucible, which remains intact after the sealing operation. We developed an improved procedure for DSC measurement for this glass capillary crucible to enable its wider adoption for thermal safety evaluation of chemical processes.

一种改进的自行完成的差示扫描量热法玻璃毛细管坩埚，用于化学过程的热安全性评估

我们介绍了一种用于DSC测量的玻璃毛细管坩埚，可以通过使用空气燃烧器加热并在冰水浴中冷却来密封玻璃坩埚。根据显微镜照片，DSC测量和热传输计算，加热对样品的影响最小。密封操作不会导致密封坩埚的玻璃发生明显变形，该变形在密封操作之后保持完整。我们开发了用于此玻璃毛细管坩埚的DSC测量的改进程序，以使其能够更广泛地用于化学过程的热安全性评估。
