1. A device comprising:
a flow unit configured to flow a gas or a liquid;
a plasma unit coupled to the flow unit and including a plurality of electrodes and a sorbent bed having a sorbent material, said plasma unit being configured to receive the flow of the gas or liquid from the flow unit so that the gas or liquid flows through the sorbent material and a predetermined chemical species in the gas or liquid is adsorbed or absorbed by the sorbent material, wherein the plurality of electrodes include a first end electrode positioned at one end of the sorbent bed, a second end electrode positioned at another end of the sorbent bed and a center band electrode positioned around the sorbent bed between the first and second end electrodes, and wherein the first and second end electrodes include a series of holes that allow the gas or liquid to flow therethrough; and
a power source providing a power signal to one or more of the electrodes, said plurality of electrodes being configured so that the power signal generates a plasma field in the sorbent material that causes the adsorbed or absorbed chemical species to desorb from the sorbent material.
