Multistation Gas/Vapour Adsorption Analysis System

气体吸附研究为各种固体材料的现代研究提供了丰富的关键信息。固体所吸附的气体的量、如何被吸附以及被吸附的能量都提供了关于固体的微观结构的重要数据，包括比表面积、孔大小和表面上的化学位置。这种基本方法有着广泛的应用，在这一应用中受到影响的研究涉及碳捕获和储存、天然气净化、新催化剂、电池更好的电极、更好的水泥和更好的石油开采方法。这六个规模可观的申请团队横跨理工科的三个系。一项非常有用的技术带来了很高的需求。这一点，再加上实验的冗长性质，意味着现有设备的排队无法管理。目前的要求是6个样品的气体吸附分析仪，以消除数月的研究瓶颈。它将把大学的无障碍分析能力从8个站点提高到14个站点。它还将允许将现有的一台设备转换为专注于关键但非常耗时的吸水分析。吸水率是实际系统中气体分离和材料性能(如烟气、防水、电极注水)的关键补充数据，该大学没有专门的仪器。

Gas adsorption studies provide a wealth of key information for the modern study of a wide range of solid materials. The amount of gas adsorbed by a solid, how it is adsorbed and the energy with which it is adsorbed all provide important data on the microstructure of a solid including surface area, pore sizes and chemical sites on the surfaces. Such a fundamental method has wide application and the research impacted in this application spans carbon capture and storage, natural gas purification, new catalysts, better electrodes for batteries, better cement, and better ways to extract oil. The six sizeable applicant teams span three departments in science and engineering. A highly useful technique brings high demand. This coupled with the lengthy nature of experiments means unmanageable queues for existing equipment. The present request is for a 6-sample gas adsorption analyzer to remove multi-month research bottlenecks. It will raise the accessible analysis capacity at the university from 8 to 14 stations. It will also permit an existing piece of equipment to be converted to focus on critical, but very time-consuming, water sorption analyses. Water sorption is a key complementary piece of data for gas separation and materials performance (e.g. flue gas, water proofing, electrode flooding) in real world systems and a devoted instrument does not exist at the university.
