UOP 791-16

This method is for determining trace amounts of sulfur species in liquefied petroleum gases (LPG) streams using a gas chromatograph equipped with a sulfur chemiluminescence detector (GC-SCD). Individual components are determined quantitatively from 0.1 to approximately 200 mass ppm sulfur. Higher concentrations of sulfur may be measured by modifying the instrument conditions to accomodate the increase in signal.
