and one or two independently heated adsorbent traps. The included external vacuum pump may be attached to
the downstream side of the traps to load a gas sample automatically, under control of the
The gas sample may be contained in Tedlar bags or canisters, or may be sampled directly from the source. The
vacuum pump is operated for several minutes or more to pass 100-200mL/minute of gas through the traps, where
the organics are retained. Several liters or more may be concentrated, depending on the detection limit required. Once
the analytes are trapped, they are desorbed and directed to the column for separation.
Shown here is a dual TO-14 Air Concentrator with four traps
and two gas sampling valves.
The TO-14 Air Concentrator comes with single or dual traps. The single trap option is good for most analyses. If vinyl
chloride is a target analyte, order the dual trap option. Please see the Purge & Trap pages for an explanation of the
benefits of our unique dual trap design.
