Engineering Research Equipment: Pulsed Field Gradient NMR Diffusion Measurements

西北大学化学工程系将采购核磁共振设备。（NMR）扩散测量在西北现有的核磁共振光谱仪。该设备包括一个扩散包，包括放大器和光谱仪软件，以及一个定制的脉冲场梯度核磁共振扩散探针。这些设备将专门用于支持工程研究。它将用于几个研究项目，包括1)沸石催化传质效应的研究，2)沸石中多组分扩散的研究，3)聚合物溶液中小分子扩散的研究，4)聚合物环境下聚合物扩散的研究，5)大块聚合物中小分子扩散的研究。作为维护核磁共振光谱仪的一般用户设施的一部分，新设备也将提供给从事其他项目的研究人员。

CTS-9610317 Snurr & Torkelson Northwestern University Project Summary The Department of Chemical Engineering at Northwestern University will purchase equipment for performing nuclear magnetic resonance. (NMR) diffusion measurements on an existing NMR spectrometer at Northwestern. The equipment con- sists of a diffusion package, including an amplifier and spectrometer software, as well as a custom-built pulsed field gradient NMR diffusion probe. The equipment will be dedicated to support research in engineering. It will be used for several research projects, including 1) and investigation of mass transfer effects in zeolite catalysis, 2) studies of multicomponent diffusion in zeolites, 3) research on small-molecule diffusion in polymer solutions, 4) studies of polymer diffusion in polymer situations and 5) investigations of small-molecule diffusion in bulk polymers. As part of the general user facility that maintains the NMR spectrometer, the new equipment will be made available to researchers working on other projects as well.
