C18 displays the typical attributes in the alkyl team - non-polar and ionically inert in most popular ailments. Retention from the C18 stationary phase arises from weak van der Waals intermolecular pressure that pulls hydrophobic compounds. C18 along with other alkyl phases like C8 and C4 represent by far the most elementary type of reverse phase H
