THT analysis in Natural Gas using DB Sulfur SCD

Hi All , I am interested in measuring sulfur species in natural gas. i know there is tbM and THT ( tetrahydrothiophene) present as odorants. but I am not seeing THT in the chromatogram. I do not have a reference standard of THT, but was wondering if there are any published methods or applications that include THT analysis with this column, to give me an idea of where it should elute. ( or it it does  ). There is Agilent application for petroleum fractions on this column with a very extensive range of sulfur species but unfortunately not THT. I would prefer not to use a different column.
