Title Purgeable Aromatics
Abstract An inert gas is bubbled through a 5 mL water sample contained in a specially-designed purging chamber at ambient temperature. The aromatics are efficiently transferred from the aqueous phase to the vapor phase. The vapor is swept through a sorbent trap where the aromatics are trapped. After purging is completed, the trap is heated and backflushed with the inert gas to desorb the aromatics onto a gas chromatographic column. The gas chromatograph is teniperattire programmed to separate the aromatics which are then detected with a photo. ionization detector 12.31.
