How Vacuum Degassers Work. A vacuum is pulled on a stream of water, and the vacuum draws the dissolved gas out of solution, removing it from water. ... In a vacuum degasser tower, water flows by gravity down through a tower filled with packing as a vacuum is drawn on the tower.

How does a degasser work in HPLC?

Online degassing is important when doing HPLC, FPLC, GPC, and uHPLC because degassing will remove dissolved gas therefore avoiding bubble formation. ... Low pressure mixing: systems are more prone to bubble formation. The solvents used for the mobile phase are mixed before the pump.

How does a vacuum degasser work?

Vacuum degasser uses vacuum to release free and dissolved gas in water, and then discharge them through the automatic exhaust valve system. ... This low gas content water is not saturated with highly absorbent for gas, it will absorb the gas in the system to achieve the gas water balance.
