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.

气体吸附研究为广泛的固体材料的现代研究提供了丰富的关键信息。固体吸附的气体量、吸附方式和吸附能量都提供了固体微观结构的重要数据，包括表面积、孔隙大小和表面的化学位置。这种基本的方法有着广泛的应用，在这种应用中影响的研究跨越了碳捕获和储存、天然气净化、新型催化剂、更好的电池电极、更好的水泥和更好的石油提取方法。六个规模可观的申请团队跨越了科学和工程的三个部门。一项非常有用的技术带来了很高的需求。再加上实验的冗长本质，意味着现有设备排起了难以管理的长队。目前的要求是一个6个样品的气体吸附分析仪，以消除数月的研究瓶颈。它将把该大学的可访问分析能力从8个提高到14个。它还将允许将现有的设备转换为专注于关键但非常耗时的吸水分析。在现实世界的系统中，吸水性是气体分离和材料性能（例如烟道气、防水、电极驱油）的关键补充数据，而大学里没有专门的仪器。
