Ionizable compound purification using reversed-phase flash

Web16 okt. 2024 · Ionizable compounds are typically water miscible and are best separated/purified using reversed-phase methods. The challenge with these water-soluble compounds is getting them to retain on hydrophobic (i.e. C18) media and elute in a tight band, the goal if you seek to purify them. Ionization (or ionisation) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
