The system of extrau00c7u00e7o in phase su00e0lida using potential prods and its process of extrau00c7u00e7o. This invention presents a system of extraction in solid phase and a solid phase extraction process using the extraction system of the invention.The invention utilizes the application of electric potentials to form an electric field in the solution present in the stationary phases extraction cartridges or disk, thereby promoting the effect of migration of charged compounds.The system of extraction of the invention and the extraction process of the invention around several limitations of techniques traditionally used and provide a new possibility for separation, recovery, elimination of interferences and the acceleration of the process of extraction in the S phase u00f3lida as a whole.
