All Chromolith® NH2 columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith® 4.6mm columns have macropores with 2 µm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å), the surface modification is NH2.

Cyano columns are generally more polar than traditional alkyl silica columns. The functional groups are highly ordered, reducing steric hindrance for the solute. The modification also allows cation exchange activity, which is higher at neutral pH than in acidic conditions. Chromolith® CN columns are suitable for the separation of alkaloids, oils, flavonoids, glycols, fenols, phthalates, steroids and sulfonamides.
