mass spectrometer for coupled TG-MS analysis

所要求的设备是一个质谱仪，设计用于分析在现有热分析（TG）系统进行的热处理过程中产生的逸出气体。质谱仪将与热重天平相结合，同时进行TG-MS分析。我小组的研究目标是开发新型多孔有机-无机杂化材料，其设计功能可用于生产高选择性吸附剂，可回收和尺寸和形状选择性固体催化剂，控制输送系统和传感装置。为了实现这一目标，研究重点是设计纳米级（1-100纳米）结构的多孔固体，并结合具有不同性质的成分的组装产生的不同功能。综合而言，我们的方法是基于在高度多孔的无机主体中定位特定功能的聚合物或有机实体，并精确控制不同功能的空间配置。有机和无机组分之间的界面、它们的局部环境以及组分在结构中的相对配置将极大地影响所得到的复合材料的性能。除了应用和技术方面，该研究项目还强调对固体基质中主客体相互作用和纳米尺度上的传输现象的基本理解，并应阐明结构和功能之间的关系。使用质谱结合热分析是必不可少的功能有机-无机杂化纳米材料的表征。特别是，这些方法的结合将使我们能够检测、识别和量化固体基质中存在的各种添加剂，指定吸附-解吸过程，评估系统的热稳定性，并研究纳米孔内的化学反应。这些综合技术将为我们的研究工作带来实质性的好处，并使我们能够迅速开发出先进应用的新材料。

The requested equipment is a mass spectrometer designed for the analysis of evolved gases that are produced during thermal treatments which  are performed with an existing thermal analysis (TG) system. The mass spectrometer will be coupled with the thermogravimetric balance for simultaneous TG-MS analyses. The aim of the research of my group is to develop new types of porous organic-inorganic hybrid materials with designed functionalities for the production of highly selective sorbents, recyclable and size-and-shape selective solid catalysts, controlled delivery systems and sensing devices. To achieve this goal, the research focuses on the design of porous solids structured at the nanoscale level (1-100 nm) and combining different functions originating from the assembly of constituents with distinct properties. Synthetically, our approach is based on locating specifically functional polymer or organic entities inside highly porous inorganic hosts, with a precise control of the spatial disposition of the different fonctionalities. The interfaces between organics and the inorganic constituent, their local environment and the relative disposition of components in the structure are expected to influence greatly the properties of the resulting composites. In addition to applications and technological aspects, the research program also emphasizes fundamental understanding of host-guest interactions within solid matrices and transport phenomena at the nanoscale, and should shed light on the relationships between structure and functions. The use of mass spectrometry combined with thermal analyses is essential for the characterisation of the functional organic-inorganic hybrid nanomaterials . Particularly, the combination of methods will enable us to detect, identify and quantify all sorts of additives present in the solid matrices, to specify adsorption-desorption processes, to evaluate thermal stability of the systems, and to investigate chemical reactions within nanopores. These combined techniques will bring substantial benefit to our research effort and allow us to develop rapidly new materials for advanced applications.
