A system and process are provided for extracting a substance from a molecular combination. The process comprises heating the molecular combination to dissociate the molecular combination into cations and anions, moving the cations and anions through a magnetic field to separate cations and anions, and isolating cations from anions with a barrier. The system comprises a non-conductive conduit for guiding an ionized particle stream, a magnetic field source for creating a magnetic field through which the ionized particle stream moves, and a barrier located in the conduit. The ionized particle stream has a velocity relative to the conduit, and the magnetic field source is oriented relative to the velocity of the ionized particle stream so that cations are separated from anions as the ionized particle stream moves through the magnetic field. The barrier is oriented in the conduit so that cations are isolated from anions after separation.
