A system for pre-concentrating analytes in a sample prior to introduction into a chromatographic column is generally disclosed comprising a housing, an adsorbent disposed in the housing, and first and second conduits having an inlet and an outlet, respectively, for transferring fluid out of and into the housing during adsorption/dry purge and desorption stages, respectively. In some embodiments, the inlet of the first conduit and the outlet of the second conduit are both disposed in one end of the housing and are offset from each other with respect to the adsorbent.
