Determine low-level sulfur in hydrocarbon gases

Consider a dual-channel gas chromatographic system as an analytical option

Firor, R. L., Quimby, B. D., Agilent Technologies

Gas chromatography (GC) with sulfur selective detection is finding widespread use in many applications. Demand for low-level sulfur detection will only increase in response to more stringent quality control and regulations. Sulfur compounds can significantly poison various catalytic processes involved in hydrocarbon and fuels processing. Monitoring these low-level poisons can lead to considerable cost reductions by improving yields, increasing catalyst life and producing higher quality products. Fuel contaminants can adversely affect fuel cell systems and fuel processors performance when they are powered from natural
