Not known Factual Statements About different types of HPLC columns
C18 exhibits the typical characteristics of your alkyl group - non-polar and ionically inert in most popular conditions. Retention from a C18 stationary period arises from weak van der Waals intermolecular force that draws hydrophobic compounds. C18 along with other alkyl phases such as C8 and C4 constitute quite possibly the most basic sort of rev
