Mobile-Phase Degassing: What, Why, and How | LCGC

Until the late 1970s, all LC systems either were run with premixed mobile phases in the isocratic mode or used high-pressure mixing to generate a gradient by mixing the mobile-phase components after the pumps. With these systems, the premixed mobile phase was degassed before use or the individual solvents were degassed for gradient applications.
