Whether you monitor hydrocarbons in refinery
streams or reactive compounds in chemical reaction
vessels, our Sulfinert
™
-treated sample cylinders and
cylinder valves will help you achieve maximum accu-
racy in your results. These inert containers ensure
the stability of sulfur compounds and other active
analytes during storage and transport from the field
to the laboratory.

Sample Cylinders and Valves
Durable, Inert Storage for Active Analytes
✔
Inert sample storage containers now available from stock.
✔
No adsorption of active compounds at low ppb concentrations.
✔
Stable, flexible surface deactivation will not crack or flake.
Sulfinert
™
-treated sample cylinders combine the
inertness of glass with the strength of stainless steel,
making them ideal for analyses of active compounds.
Restek's exclusive Sulfinert
™
process creates a thin,
silica-like layer on the stainless steel surface. Even at
trace levels, sulfur compounds and other active mol-
ecules can be collected and stored in these cylinders
with no significant loss. Effectively incorporated into
the steel surface, the Sulfinert
™
layer cannot chip,
flake, or rinse off - even under stringent sampling,
transport, or cleaning conditions.
All sample-contacting surfaces in our Sulfinert
™
-
treated sample cylinder valves are equally inert,
making these components ideally compatible with
Sulfinert
™
-treated sample cylinders.
Sulfinert
™
-treated gas sampling apparatus is ideal for
applications that demand only inert surfaces contact
the sample, such as sampling natural gas streams or
testing beverage-grade carbon dioxide. For other
Sulfinert
™
-treated sample pathway components, refer
to our current general catalog, or contact our
Technical Service group or your Restek representative.
