Restek Sampling Equipment Helps Assure Accurate Data

By Irene DeGraff, Air Monitoring Product Marketing Manager

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

Increase Accuracy & Efficiency

Air Canister Heating Jacket—The ultimate in controlled heating, for reliably cleaning your air canisters!

Our heating jacket can help you prepare your canisters for sampling faster and more efficiently. The jacket’s novel design ensures complete cleaning by heating the canister and valve together. When used during the analysis, it prevents condensation, ensuring more accurate results. Two temperature settings, 75°C and 150°C. Fits all canisters up to 6L in size.
