Patent ID: 8753584

Claim:
A system or device for biochemical analysis comprising: a plurality of fluid lines configured to have liquids flow therethrough for biochemical analysis; and at least one electroosmotic (EO) pump configured to pump the liquids through the plurality of fluid lines, the at least one EO pump comprising: a housing having a pump cavity; a porous core medium positioned within the pump cavity to form an exterior reservoir that extends at least partially about an exterior surface of the porous core medium, the porous core medium having an inner chamber provided therein, the inner chamber representing an interior reservoir; and electrodes positioned in the inner chamber and positioned proximate the exterior surface, the electrodes configured to induce a flow of the corresponding liquid through the porous core medium between the interior and exterior reservoirs, wherein a gas is generated when the electrodes induce the flow of the corresponding liquid; the housing having a fluid inlet to convey the corresponding liquid to one of the interior reservoir and the exterior reservoir, the housing having a fluid outlet to discharge the corresponding liquid from another of the interior reservoir and the exterior reservoir, the housing having a gas outlet to discharge the gas from the pump cavity.
