    |  The SRI Method TO-14 
        Air Concentrator is equipped with a vacuum pump 
        and interface, a 10-port gas sampling valve, 
        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 PeakSimple 
        data system. 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. |
