| 摘要: |
| 建立了一种利用程序升温气相色谱仪的逸出气体检测(EGD)系统，用于测量液薄膜、固薄膜、纤维、粉末等材料中微量的热挥发及（或)挥发性热分解组分。这类微量用常规热分析法(如热重法(TG)、微商热重(DTG)及差热分析(DTA)等)一般难以测出。用该法测量的CuSO4?5H2O粉末样品、端羟基聚丁二烯(HTPB)及邻苯二甲酸二丁酯(DBP)薄膜样品逸出气的EGD数据同TG-DTG-DTA联用技术所得结果作了比较。还用该系统检测了硼酸 (槽浴)阳极氧化铝箔、碳纤维、碳化硅纤维的逸出气体。阐述了本法的优点及具体步骤。 |

| Abstract: |
| An effluent gas detection (EGD) system by programmed temperature gas chromatography had been developed for measuring the micro contents of thermovolatile and volatile thermodecomposition components evolved from the liquid and solid thin films，fibers，powders etc，during the heating of cited materials. These micro contents Were difficult to measure by the conventional methods of thermal analysis (Such as TG，DTG and DTA). The EGD data of evolved gases from the powdered sample of CuSO4?5H2O and the film samples of hydroxy terminated polybutadiene(HTPB) and dibutyl phthatate(DBP)，measured by EGD system were compared with the correspondent data obtained from TG-DTG-DTA technique. The anodic oxidation aluminum foil in boric acid bath，carbon fibre and silicon carbide fibre Were also measured by cited EGD system. The advantages and procedure Were described. |
