Urgent replacement of a thermogravimetric analyzer and upgrade with a mass spectrometer

这项建议的目的是用新的热重分析仪(TGA)取代旧的热重分析仪，并通过增加质谱仪(MS)来升级仪器。该TGA-MS将用于UQAM化学系和INRS-EMT的材料表征。首先，我们部门迫切需要一个新的TGA，因为现在的旧TGA已经快用完了。其次，在热重分析中加入质谱仪将为我们提供一个无价的材料表征工具。TGA-MS技术是能源转换、材料科学、聚合物科学和生物材料领域的各种研究计划/项目所必需的。所要求的TGA-MS系统可用于：i)改性碳、金属和金属氧化物的表征；ii)碳纤维回收热解废气的气体分析；iii)通过催化聚合制备线键涂层的研究；iv)用于能源应用和检测水中新出现的污染物的杂化材料的合成。除了对下文所述的具体研究项目产生重要影响外，获得这一TGA-MS系统对于我们两个机构的培训工作将是必不可少的。根据我们目前TGA过去的使用情况，每年将至少有25名HQP使用TGA-MS系统。

The aim of this proposal is to replace our old thermogravimetric analyzer (TGA) by a new one and upgrade the apparatus by addition of a mass spectrometer (MS). This TGA-MS will be used for materials characterization in the Chemistry Department of UQAM and at INRS-EMT. Firstly, a new TGA is urgently needed in our department because the current old one has almost reached the end of its useful lifetime. Secondly, the addition of a MS to the TGA will provide us with an invaluable tool for materials characterization. The TGA-MS technique is required for various research programs/projects in the area of energy conversion, materials science, polymer science and biomaterials. The requested TGA-MS system can be used for:i) the characterization of modified carbons, metals and metal oxides; ii) gas analysis of waste gas from carbon fiber recovery pyrolysis; iii) studies dealing with the preparation of coatings for wirebonds prepared by catalytic polymerization and iv) the synthesis of hybrid materials for energy applications and detection of emerging pollutants in water. Beyond its important impact on the specific research programs described below, acquisition of this TGA-MS system will be essential for training efforts in our two institutions. Based on the past utilization of our current TGA, a minimum of 25 HQPs will be using the TGA-MS system every year.
