Building on recent advances in low temperature DNP methods for producing hyperpolarized (HP) Xe-129 for MRI applications, we explore DNP efficiency of homogeneously mixed Xe/1-propanol/trityl radical mixtures in the solid-state using a newly developed apparatus and evaluate the utility of NMR observables as probes of sample heterogeneity.
