ABSTRACT: International environmental regulations have created the need for sensitive, accurate, and reproducible analytical tools to measure ultralow sulfur concentrations in fuels, such as diesel and gasoline. In this work, a sensitive, accurate, and reproducible analytical methodology to measure ultralow sulfur concentrations in desulfurized diesels (
