Not known Factual Statements About different types of HPLC columns
C18 displays The standard features in the alkyl team - non-polar and ionically inert in most commonly encountered problems. Retention from a C18 stationary section originates from weak van der Waals intermolecular power that attracts hydrophobic compounds. C18 together with other alkyl phases for instance C8 and C4 constitute by far the most essent
