Abstract
Methods of detecting a sulfur-containing compound in a sample are described, for example using NMR-SABRE hyperpolarization of the sulfur-containing compounds in the sample. The methods can comprise, for example, contacting a sample comprising a sulfur-containing compound with parahydrogen and a catalyst to form a mixture. A spin order can be transferred from the parahydrogen to the sulfur-containing compound thereby hyperpolarizing the sulfur-containing compound during a temporary association of the parahydrogen, the sulfur-containing compound, and the catalyst. The methods can further comprise, for example, performing an NMR measurement on the mixture comprising the hyperpolarized sulfur-containing compound to detect the hyperpolarized sulfur-containing compound (e.g., from the hyperpolarized NMR signals. In some examples, the methods described herein can be used for detecting a sulfur-containing contaminant in a fuel.
