摘要 热分析-红外-质谱联用系统结合了同步热分析仪与傅立叶变换红外光谱仪和质谱仪的优点,该联用系统不需对样品进行前处理而直接进行样品分析。该联用系统能实时、直观的了解样品在整个升温程序中的热重、热效应和红外数据变化,监测不同时刻、不同温度下样品所释放物质的种类与含量,适用于对复杂及混合样品化学组成及热分解过程进行详细分析。本实验将热分析-红外-质谱联用系统用于石墨烯材料的组成与热分解行为分析。 STA-FTIR/MS combines the advantages of TA,FTIR and MS,and the coupling system can analyze samples without pretreatment.STA-FTIR/MS can record the changes of the mass,heat effect and FTIR of the samples on-line and in real time.The detection mode of monitoring the types and content of the evolved gas under different temperature and time conditions suits to analyze the chemical components and thermal decomposition process of complex samples and mixed systems.
