The unique properties of Nickel create the best combination of inertness, low carryover, and replaceability, so you never have to throw away a fitting, flow controller, (or worse) a 6L canister because your ferrule or ¼” Swagelok style nut failed you.. Too often, sampling professionals set out a canister and flow controller, only to find that it either under or over samples by the time they return. 41901: EPA TO-14A Aromatic Subset Mix 100 ppb in nitrogen, pkg of 110 L (pi-marked cylinder), analytical standard : Select the promotions of interest and our team will contact you to get started. Quantity. Flow controllers (or flow restrictors) are essential equipment for the collection of vapor samples with Summa canisters. Les Jones, CEO says, “The addition of Summa air monitoring canisters extends our already comprehensive range of environmental testing services available to the industry. The Summa canister will be equipped with a pressure AMC’s are of great concern to any sensitive micro-electronics manufacturing process, especially in nano-technology applications. Many sampling professionals have asked us for tool-free connections and we’ve delivered on this. SUMMA canisters. This device connects to the CS1200E and operates through a Microsoft Windows interface where canister size, sampling duration, target end pressures, and elevations can be entered. EMSL Product Catalog Summa Canisters. FOR FURTHER INFORMATION - PLEASE CONTACT: Rachel Hogrefe, Phone: (573) 522-9844.
