Abstract: | Steam distillation is combined with solid-phase resin extraction using a simple apparatus and interface. A concentration factor of at least 100 is obtained. The method is effective for the isolation and concentration of organic compounds from complex aqueous samples ar μg l?1 levels. Factors affecting the recovery of model compounds are studied; it is shown that the recovery of many compounds is improved markedly by disconnecting the condenser. Under proper conditions, compounds with boiling points in excess of 400°C are recovered quantitatively in only 24 mill. |
