本工作根据所选择的分离柱和裂解气相色谱操作条件,定性鉴定了各种高聚物裂解产物中的特征峰,建立了一套适用于实验室条件下的各种聚合物的标准裂解指纹图,并用该谱图鉴定和剖析了许多未知的高聚物。CO_2激光裂解气相色谱仪可以直接用于浅色或无色透明样品的分析。它具有灵敏度高、分析速度快、设备简单、成本低以及“二次反应”少和重复性好等特点。
In this work, according to the selected separation column and pyrolysis gas chromatography operating conditions, qualitative identification of the characteristic peaks of various polymer lysis products, established a set of standard lysis fingerprints suitable for various polymers under laboratory conditions , And used this spectrum to identify and dissect many unknown polymers. The CO 2 laser pyrolysis gas chromatograph can be used directly for the analysis of light or colorless, transparent samples. It has the characteristics of high sensitivity, fast analysis, simple equipment, low cost, less secondary reaction and good repeatability.
