The Infrared (IR) microspectroscopy system was purchased in 2007 and installed at the Electrochemical Technology Centre (ETC) of the University of Guelph (UoG). It includes: (i) a Nicolet Nexus 870 FT-IR spectrophotometer, (ii) a PM-IRRAS Module for Nicolet Nexus 870, (iii) a Continuum FT-IR Microscope, (iv) a diamond attenuated total internal reflection (ATR) accessory, and (v) an IR purge gas generator. The IR microspectroscopy system has been configured to characterize various materials and interfaces, including solid-solution and electrochemical interfaces. It provides several advanced spectroscopic techniques such as localized ATR spectroscopy, photon polarization infrared reflection absorption spectroscopy (PM IRRAS), subtractively normalized interfacial Fourier transform spectroscopy (SNIFTIRS), and surface enhanced infrared reflection absorption spectroscopy (SEIRAS). The IR microspectroscopy facility has been extensively used over the last 14 years. Although the IR microscope, ATR, and gas generator continue to function very well, the FT-IR spectrophotometer and PM-IRRAS Module have reached the limits of their lifespans and are dysfunctional. As the suppliers and associated servicing for the 870 FT-IR spectrophotometer and PM-IRRAS Module for the Nicolet Nexus 870 have been discontinued, it is necessary for us to replace them with the new Nicolet iS50R FT-IR spectrophotometer and its advanced PM-IRRAS Module, which incorporate the latest electronic and digital technology for advanced continuous scan, step-scan, and dual-channel applications. The proposed critical upgrade will enable a completely functioning system that is urgently required to support a number of NSERC funded research programs at UoG. In particular, the innovative research programs of the applicant (Professor A. Chen) and co-applicants (Professor L. Chen, J.R. Dutcher and J. Lipkowski), and the major users (Professor F.-I. Auzanneau, H. Li, E. Pensini and Dr. Q. Wang). The IR microspectroscopy system is a unique research facility at UoG and this region. It is located at the ETC, and is easily accessible by students and researchers on campus and across this region. The Manager of the ETC will continue to maintain the facility and to provide hands-on training. All trained students, postdoctoral fellows, and research associates will run their samples and analyze the spectra. It is anticipated that the upgraded IR microspectroscopy system will be in operation every day for over 180 hours per month by the research teams of the applicant, co-applicants and major users alone. Additional time will be required by users from the Departments of Chemistry and Physics, and the School of Engineering. It is essential for student training and will facilitate further regional, national, and international collaborations toward the development of advanced clean technologies to address increasingly critical energy, environmental, and health issues.

红外（IR）微光谱系统于2007年购买，并安装在圭尔夫大学（UOG）的电化学技术中心（ETC）。它包括：（i）Nicolet Nexus 870 FT-IR分光光度计，（ii）Nicolet Nexus 870的PM-IRRAS模块，（iii）连续ft-ir显微镜，（iv）钻石衰减的总内部重新分配（ATR）配件和（v）Ir Purge Generator。 IR微光谱系统已配置为表征各种材料和界面，包括固体溶液和电化学接口。它提供了几种晚期光谱技术，例如局部ATR光谱，光子极化红外反射吸收光谱（PM IRRAS），分类归一化的界面傅立叶变换光谱（Sniftirs）和表面增强的红外红外反射吸收光谱（SEIRAS）。在过去的14年中，IR微光谱设施已广泛使用。尽管IR显微镜，ATR和气体发生器继续运作良好，但FT-IR分光光度计和PM-IRRAS模块已达到其寿命的极限，并且功能障碍。作为供应商以及与Nicolet Nexus 870的870 FT-IR分光光度计和PM-IRRAS模块相关的服务，我们有必要用新的Nicolet IS50R IS50R FT-IR SpectroPhotophorometometom计及其先进的Electran-Digital-Digital-Digital-Electry-nicker-nicle-pm-irras scan和Digital-Digital-Scan scan scan and-scan scan scan scan and-scan scan scan and-pm-irras替换。拟议的关键升级将使迫切需要一个完全运行的系统，以支持UOG的许多NSERC资助的研究计划。特别是，申请人（A. Chen教授）和共同申请者（L. Chen教授，J.R。Dutcher和J. Lipkowski）的创新研究计划以及主要用户（F.-I。Auzanneau，H。Li，H。Li，E。Pensini和Q. Wang博士）。 IR微光谱系统是UOG和该地区的独特研究机构。它位于ETC，校园和该地区的学生和研究人员很容易获得。 ETC的经理将继续维护设施并提供动手培训。所有训练有素的学生，博士后研究员和研究伙伴将运行样本并分析光谱。可以预计，仅申请人，共同申请者和主要用户的研究团队，升级后的微光谱系统每天将每天运行180多个小时。化学和物理学系以及工程学院的用户将需要额外的时间。这对于学生培训至关重要，将促进进一步的区域，国家和国际合作，以开发高级清洁技术，以解决日益关键的能源，环境和健康问题。
