Solvent degassing is the removal of particulate matter and dissolved gases in solvents. Most instrument manufacturers recommend filtration and degassing of solvents and samples prior to analysis.

Particulate matter and dissolved gasses in solvents can create false peaks or baseline instability. Researchers use degassing to reduce instrument down time, extend column life and optimise instrument performance, solvent must be degassed using a vacuum pump.

The key issues to consider when selecting a vacuum pump are: (1) type of solutions, vapours and gasses being degassed; (2) the ultimate pressure required to degas;  and (3) pumping speed of vacuum pump.
