It also finds use in amino acid separations and protein purification protocols. Even though ionpair chromatography also separates ionic and ionizable compounds, it is normally lumped with reversedphase chromatography as it employs exactly the same packing supplies. Lots of chromatographers knowledgeable about reversed-period chromatography choose to use ion-pair chromatography for ionic and ionizable compounds as the columns tend to be more common to them plus the ideas of reversed-stage chromatography could be typically used in technique progress.
