Because they contribute to air pollution and are known catalyst poisons, sulfur compounds are increasingly
being targeted for monitoring to extremely low levels in air and in ethylene/propylene. Strict limits for
sulfur content in gasoline and diesel fuel are to be achieved by 2007.
Many key organo-sulfur compounds are adsorbed to or react with steel or stainless steel surfaces. To address
this issue Restek developed the Sulfinert® surface treatment process. Sulfinert® treatment eliminates
interaction between organo-sulfur compounds and steel. The figures
demonstrate the benefit
of using Sulfinert®-treated components for sampling and storing organo-sulfur compounds
Refineries and petrochemical plants use Sulfinert®-treated components for sampling, and for transferring
sample streams. Natural gas and liquid propane gas manufacturers and transfer companies rely on
Sulfinert®-treated systems to accurately quantify sulfur-containing odorants in natural and liquid propane
gas streams. Sulfinert®-treated sampling equipment is specified in International Society of Beverage
Technologists methods for determining sulfur impurities in beverage grade carbon dioxide. (ISBT procedure 1.0)
A wide variety of Sulfinert®-treated items are available from stock, including tubing, fittings, sample
cylinders, valves and sampling components. If you have other requirements, please see
