Executive Summary Our department has currently many equipment's to properly analyze and characterize polymeric and solid-state chemistry. However, we lack the ability to properly characterize the properties of novel material such as their degradation profiles, thermal stability, mass loss, change in crystal shape, crystallographic space group, volume, pyrolysis, combustion processes, or activation energies. Instrument Requested A Thermogravimetric Analyzer with Fourier Transform Infrared Capability (TGA-FTIR). Description of Instrument This equipment is utilized to combine thermogravimetric analysis (TGA) with the identification power of an FTIR spectrometer. TGA measures the change in sample weight as a function of temperature or time in a controlled atmosphere, which is usually accompanied by an evolution of gases caused by sample decomposition or volatilization. The weight loss corresponds to the evolved gas components associated with volatilization or degradation of the material. Coupling the TGA to an FTIR spectrometer, enables the evolved gases to be chemically identified and help to elucidate information on materials heat stability, degradation temperatures, residual solvent levels, absorbed moisture content, amount non-combustible content, and to the nature of the decomposition process. Equipment Request and Reason for Proposed Configuration: The equipment request is to build a dual TGA-IR equipment. Depending on the user, both equipment can be used independently for material characterization, or utilized in tandem to characterize material thermal stability and identification of the volatile by FTIR. Research Activity This equipment will be shared amongst 3 primary users listed here as applicant and co-applicants at Ryerson University (RU) in the department of Chemistry & Biology and the department of Chemical Engineering. It will also be available to other researchers at RU.

执行摘要 我们部门目前拥有许多设备来正确分析和表征聚合物和固态化学。然而，我们缺乏正确表征新型材料特性的能力，例如它们的降解曲线、热稳定性、质量损失、晶体形状的变化、晶体空间群、体积、热解、燃烧过程或活化能。 所需仪器 具有傅里叶变换红外功能 (TGA-FTIR) 的热重分析仪。 仪器说明 该设备用于将热重分析 (TGA) 与 FTIR 光谱仪的识别能力相结合。 TGA 在受控气氛下测量样品重量随温度或时间的变化，这种变化通常伴随着样品分解或挥发引起的气体逸出。重量损失对应于与材料的挥发或降解相关的放出气体成分。将 TGA 与 FTIR 光谱仪耦合，可以对逸出的气体进行化学鉴定，并有助于阐明有关材料热稳定性、降解温度、残留溶剂水平、吸收水分含量、不可燃含量以及分解性质的信息过程。 设备请求和建议配置的原因：设备请求是构建双 TGA-IR 设备。根据用户的不同，这两种设备可以独立用于材料表征，也可以串联使用来表征材料的热稳定性并通过 FTIR 识别挥发物。 研究活动 该设备将由此处列出的瑞尔森大学 (RU) 化学与生物系和化学工程系的申请人和共同申请人的 3 个主要用户共享。 RU 的其他研究人员也可以使用它。
