Continuous Flow NMR with Hyperpolarized Xenon for the Characterization of Materials and Processes

Abstract

129Xe NMR spectroscopy with a continuous flow of dilute hyperpolarized xenon directed into the sample region of an NMR probe (either static or spinning) allows the rapid recording of spectra that are characteristic of the void space in micro- and mesoporous solids. The high sensitivity of the method allows the time-resolved, in-situ monitoring of processes involving sorbents such as activation, adsorption, and desorption.
