Air Sampling

One of the most widely used methods for ambient air monitoring, USEPA TO-15, specifies sample collection with a specially pre-

pared stainless steel canister, followed by GC/MS analysis. Restek can support all facets of this or other air monitoring programs –

from state-of-the-art sampling equipment to high quality analytical reference standards.

An inert canister surface is critical to obtaining accurate sample results. Restek offers a complete line of TO-Cans™ (Summa® equiv-

alent canisters) which are electropolished and extensively cleaned prior to shipping to ensure a high-quality passivated surface for

improved analyte stability. No weld marks on the spheres further reduce the occurrence of active sites. For reactive compounds, such

as sulfur-containing components, a SilcoCan™ is your best canister choice. SilcoCan™ canisters are deactivated with Siltek® surface

treatment ensuring exceptional inertness and maximum sample stability, even for low level sulfur compounds.

TO-Can™ Air Monitoring Canisters

Restek canisters are originally equipped with high-quality Parker Hannifin diaphragm valves. Each valve is helium leak-tested to 4 x
