Field duplicates of canister samples frequently result in analyte concentrations with high relative standard deviations. In addition, field duplicates do not differentiate laboratory performance from sampling variability. Restek’s dual canister sampling manifold (DCSM) minimizes sampling variability through a single sample inlet and flow controller by which the sample is evenly collected between two canisters. Use of a single flow controller eliminates flow rate variability, as well as environmental variables common with collocated samples. The DCSM may also be used with two flow controllers to monitor individual canister vacuum. Note: Do not use the DCSM as a handle to pick up 2 canisters!

特点与优势

• Duplicate sampling with all canister sizes using one or two flow controllers.
• Precise dimensions (9.5" wide x 3.5" high) provide accurate splitting of sample between two canisters.
• One-piece design means fewer leaks.
• Thick-walled stainless steel tubing is rugged enough for field use.
• Uses 1/4" compression connections.
