Now featuring all new low flow stability for extremely precise Time Weighted Average
Low-Level TO-15 monitoring requires consistent analyte recovery while collecting the maximum sample volume possible to support larger preconcentration volumes or repeat analyses from the same canister. The CS1200E will reliably fill canisters at a constant rate with a better-demonstrated recovery of TO-15 compounds than any other sampler.
Time-weighted average VOC concentrations can be easily determined by sampling into canisters at a constant flow rate. Canisters can be filled to nearly atmospheric pressure using an ultra-clean, mechanical flow controller. Sapphire orifices combined with pressure regulation offer superior flow stability when compared to needle valve or frit regulated controllers. Different orifices are available to fill a 6L canister over 1, 3, 8 or 24 hours, or even 1–2 weeks. Part numbers for CS1200E flow controllers are separated by flow range. One flow range can be changed to another by attaching the appropriate critical orifice shown in the table below. SiloniteTM coated flow controllers are designated with an “S” following the part number.
