Dual Canister Sampling Manifold
(Stainless Steel & Siltek®-Treated)
• 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

compression connections.
Field duplicates of canister samples frequently result in analyte concentrations with
high relative standard deviations. In addition, field duplicates do not differentiate labo-
ratory performance from sampling variability. Restek’s dual canister sampling mani-
fold (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 DCSMmay also be used with two flow control-
lers to monitor individual canister vacuum.
