Gas Chromatography (GC)

Online gas chromatography is used to generate real-time compound speciated data. Our Analytical Services team has a wide variety of expertise in direct-sampling and quantifying specific compound emissions using gas chromatography. Various compounds are speciated and quantified using the following test methods:

Method 15

Utilized to measure the emissions of reduced sulfur compounds from tail gas control units of sulfur recovery plants, hydrogen sulfide in fuel gases and where specified in other applicable subparts.

Method 16

This method determines total reduced sulfur compounds from recovery furnaces, lime kilns and smelt dissolving tanks at kraft pulp mills and fuel gas combustion devices at petroleum refineries.

Method 18

Speciated gaseous organics emitted from industrial sources are determined by this method.
