Not known Factual Statements About different types of HPLC columns
C18 displays the typical characteristics of the alkyl team - non-polar and ionically inert in commonest disorders. Retention from a C18 stationary period comes from weak van der Waals intermolecular pressure that attracts hydrophobic compounds. C18 together with other alkyl phases which include C8 and C4 represent by far the most essential type of
