For ultimate inertness, SilcoCan air sampling canisters feature our unique Siltek treatment technology. Even highly active components at low parts-per-billion concentrations can be readily sampled and stored without loss. The valve is a high-quality, metal-to-metal seal, 2/3-turn valve with metal diaphragms to prevent sample adsorption for more accurate results. Both stainless-steel and Siltek-treated valves are available in both the 2-port and 3-port configurations. Each canister is slightly pressurized with contaminant-free nitrogen prior to shipment.
Whether you are sampling for TO-14A, TO-15, TO-15A, or reactive sulfur compounds, SilcoCan canisters are your best choice for inertness. In Tedlar bags, the stability of low-level (100 ppbv) sulfur volatile organic compounds (VOCs) is poor, even within 24 hours of sampling. Sulfur compounds react with the metal surface in electropolished canisters, so they are unsuitable for collecting and storing low-level sulfur VOCs. SilcoCan air sampling canisters, which feature a Siltek-treated surface, offer excellent storage stability for sulfur VOCs at very low levels (5–20 ppbv), under dry or humid conditions. The versatility of the SilcoCan canister makes it an excellent choice for collecting and storing TO-14A, TO-15, or TO-15A compounds.
