Abstract
A flow-dampening degassing apparatus for transport of liquid chromatography fluids therethrough includes a substantially burdoin-shaped flexible tube disposed in a reduced-pressure chamber, the tube being sufficiently flexible to expand in a cross-sectional direction upon incursion of a fluid pulsation to thereby increase an inner volume of the tube and correspondingly reduce fluid pressure therein. In a particular embodiment, the tube is fabricated from a gas-permeable and liquid-impermeable material for degassing transported fluids in the reduced-pressure chamber.
