different types of HPLC columns Fundamentals Explained
C18 exhibits the typical features of the alkyl team - non-polar and ionically inert in most common problems. Retention from a C18 stationary phase arises from weak van der Waals intermolecular force that pulls hydrophobic compounds. C18 along with other alkyl phases like C8 and C4 represent the most basic variety of reverse stage HPLC.Silica column
