, one example is, reveals retention moments for four weak acids in two cell phases with just about similar values for (P^ key ). Even though the order of elution is similar for equally cell phases, each solute’s retention time is afflicted in different ways by the selection of organic and natural solvent.Detector – responds to the separated an
