Not known Factual Statements About different types of HPLC columns
C18 reveals The standard capabilities in the alkyl group - non-polar and ionically inert in most popular conditions. Retention from a C18 stationary phase arises from weak van der Waals intermolecular drive that pulls hydrophobic compounds. C18 along with other alkyl phases for instance C8 and C4 represent quite possibly the most elementary form of
