Main Question or Discussion Point

What's the purpose of the regulated helium source going into the solvent reservoirs in HPLC? Is it just to degas the solvents? Does it have any other use?

It degasses the solvents and provides a blanket of Helium over the reservoir to prevent air from dissolving back into the solvent.
