方法空气浓缩器
The SRI 方法空气浓缩器 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 100-200mLs/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.

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.
