Trace Sulfur Analysis

Add Bookmark

Sulfurs present in natural gas and natural gas liquids are known catalyst poisons in the refining process and can cause excessive smog and SOx emissions when burned as a fuel. With increasing restrictions on the amount of allowable sulfur in fuels, a reliable, sensitive, and accurate sulfur analyzer is critical for any midstream testing lab. At Shimadzu we have combined our world class sulfur chemiluminescence detector (SCD) with our best in class GC-2030 gas chromatograph to deliver the ultimate solution for sulfur analyses in hydrocarbon and other gaseous streams.
