Abstract
A liquid chromatography system has a reservoir for the mobile phase with a cap which provides for effective control of charging the reservoir with the mobile phase, sparging the mobile phase while it is in the reservoir, feeding the mobile phase to the chromatograph, returning the mobile phase to the reservoir after it has passed through the chromatograph, venting or vacuumization of the reservoir and providing for automatic release of overpressure within the reservoir, all while maintaining the sparged environment in the reservoir.
Claims14
A sealed liquid chromatography system comprising a liquid chromatograph, a vessel for solvent to be used in said system, first means operatively connected to said vessel for controllably sparging said solvent, second means operatively connected to said vessel for feeding said solvent from said vessel to said chromatograph, and third means operatively connected to said vessel and to said chromatograph for returning said solvent to said vessel after it has passed through said chromatograph, said second and third means and said vessel defining, in conjunction with said chromatograph, a sealed system for said solvent.
