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

cc/sec. The all-stainless steel construction eliminates contamination and withstands temperatures from -100°C to 250°C.
