Solvent degassers
All liquids contain dissolved gases which are readily absorbed from the air. In solvents for liquid chromatography, dissolved gases reduce pump flow rate stability, detector baseline stability.
The degassing unit is placed in-line between the solvent reservoir and the inlet of the pump. The action of the pump draws the liquid from the reservoir through the degasing unit. Solvent is drawn through fluoresin membranous tubing which is permeable to the dissolved gases. Hence, gases will permeate out by vaccum through the tubing.
Models available from micro HPLC to preparative applications.
