Not known Factual Statements About different types of HPLC columns
C18 displays The standard options from the alkyl team - non-polar and ionically inert in most common problems. Retention from a C18 stationary section arises from weak van der Waals intermolecular pressure that pulls hydrophobic compounds. C18 together with other alkyl phases like C8 and C4 represent essentially the most fundamental style of revers
