"热重分析中的气氛 (The Atmosphere in TGA/STA)

Tuesday, October 26, 2021 | 10:00 - 11:00 AM CST (Beijing Time)

在热重(TGA/STA)分析测试中,与试样相接触的气氛十分重要,不同的实验气氛条件下得到的热分析曲线不尽相同。本讲座介绍了热分析测试中可供选择的各类气氛的特征、选择原则、测试案例及其相关的注意事项。测试前,应结合实验目的来选择合适的实验气氛;测试后,在对所得到的曲线进行解析时,必须清楚地了解实验时所采用的气氛对曲线的影响程度;此外,对于特殊气氛的测试,还需注意其特殊配置的选择,并充分评估其对仪器的安全性,以防对仪器造成不可逆的损害。

The atmosphere plays a vital role in the thermogravimetry analysis (TGA)   and  simultaneous thermal analysis (STA). It was found that changing of the applied atmosphere affects different thermal decomposition behaviors which result in different thermal curves. Here, this lecture makes an introduction of the characteristics , choice principles,  test cases and some related considerations of various atmospheres in the thermal analysis. First,the appropriate atmosphere should be selected according to the experiment purpose. Then, the influence of atmosphere on the thermal curve must be understood clearly. Moreover, for special atmosphere, the relevant configurations are needed. Also, the safety of atmosphere on instruments should be estimated to protect apparatus from damage.
