WebDegassing is the deliberate removal of gas from a solid or a liquid. How is oxygen removed from water? Four common techniques for the removal of dissolved oxygen from water have been examined: boiling at 1 atm, boiling under reduced pressure, purging with N 2 and sonication under reduced pressure. Perrine Juillion WebDegassed solvent in a sealed Schlenk flask can usually be kept for 1-2 days. Atmosphere Exchange Under Sonication Solvents can be roughly degassed by repeated sonication under light vacuum (i.e. house vacuum) for 0.5-1 min and replenishing the atmosphere with an inert solvent. http://www.chem.rochester.edu/notvoodoo/pages/how_to/degas_solvents.php o365 emails not being received
