Laboratory Total Sulfur Analysis by Gas Chromatography and Agilent Model 355 SCD

Abstract: Gas chromatography with sulfur chemiluminescence detection (SCD) provides a relatively quick means to identify and quantify sulfur compounds that are present in petroleum and petrochemical feeds and products, such as natural gas, ethylene, propylene, liquefied petroleum gases, solvents, gasoline, and diesel fuels. In many cases, it is sufficient to simply measure the total sulfur content of a sample without the need for compound speciation. If that is the case, one can replace the GC column with an appropriate transfer line to connect the injector with the detector. This technical overview briefly covers the rapid determination of total sulfur using a GC as a sample introduction device and the SCD to quantitate the sulfur content of a sample.
