Sulfinert® Treated Swagelok® Sample Cylinders

Technical Article: Stable Sulfur and Mercury Sampling in Refineries

Sulfinert® coating provides stable storage of sulfur and mercury at ppb levels in petroleum samples.
Inert coating doesn't flake; more durable than Teflon®.
TPED compliant cylinders now available for shipping into EU countries.
All cylinders have 1/4" female NPT threads on both ends.

Refinery and natural gas samples often contain trace amounts of sulfur-containing compounds which can interfere with reactions or poison catalysts in petrochemical processes. Because sulfur compounds quickly react with stainless steel surfaces, accurate determination of these compounds is impossible when samples are collected and stored in untreated sample cylinders. Restek's Sulfinert® passivation technique bonds an inert silica layer into the surface of stainless steel, preventing active compounds from reacting with or adsorbing to the steel. These Swagelok® high pressure sample cylinders are Sulfinert® treated for greater stability of sulfur compounds and mercury. DOT rating to 1,800 and 5,000psig allows sampling at gas wellheads as well as in the refinery. Use of high pressure sample cylinders is cited in ASTM D1265, Standard Practice for Sampling Liquefied Petroleum (LP) Gases, Manual Method.
