Apparatus for solvent degassing and solvent supply in liquid chromatographs

摘要

An apparatus for solvent degassing and solvent supply in a liquid chromatograph comprises at least one solvent storage vessel, the volume of which is partly filled with liquid solvent while the remaining volume forms a vapor volume. A helium source is connected to said vapor volume for avoiding re-absorption of air by the solvent. A vacuum pump is connected to said vapor volume via a suction line, and a solvent source is connected to said vapor volume via a supply line. A pore filter terminates said supply line within said vapor volume.
