Answer:The G7122A Infinity II/III degasser.
Answer:Removal of dissolved gases from liquid chromatography mobile-phase solvents.
Answer:No. It creates vacuum for degassing rather than driving solvent through the analytical column.
The Agilent internal degasser vacuum pump is a replacement mechanical service component for compatible Infinity II and Infinity III liquid chromatography degasser units, including the G7122A model. The pump creates the low-pressure conditions used inside the degassing system to remove dissolved gases from mobile-phase solvents before they reach the LC fluid path. Efficient solvent degassing can help minimize bubble formation, noisy baselines and irregular pump operation. This component is part of the instrument's solvent conditioning hardware, not an HPLC high-pressure delivery pump or an LC–MS roughing pump. Selection must match the degasser module configuration during scheduled or corrective maintenance.
