Abstract
A vacuum degassing and solvent delivery apparatus for those solvents being utilized in high pressure liquid chromatographic operations and/or applications. The degassing and delivery apparatus of the present invention is designed for attachment directly to a solvent reservoir, such as a double-ended bottle having a threaded portion along the bottom end thereof. The arrangement facilitates ease of installation and removal of the vacuum degassing, recycling and delivery apparatus so as to accommodate a variety of installation applications and requirements. The solvent degassing system of the present invention further includes the utilization of an atmospheric impermeable composite tubing structure which is effective for isolating fluids from atmospheric contamination during transport.
