“Phenyl 120 Å Preparative Columns” are good for
Separation of aromatic and polar compounds — The phenyl stationary phase exploits π–π interactions (i.e. aromatic rings in the analytes interacting with the phenyl rings in the stationary phase), in addition to normal reversed-phase hydrophobic interactions. This often gives better separation for aromatic compounds than traditional alkyl (C8/C18) columns.
Preparative-scale purification — As a “preparative” column, this type is meant not just for analytical detection but for isolating and collecting sizable amounts of purified compounds (e.g. APIs, natural products, intermediates, impurities, small molecules from synthesis)
