C18 displays The standard functions on the alkyl group - non-polar and ionically inert in most typical conditions. Retention from the C18 stationary phase emanates from weak van der Waals intermolecular power that draws hydrophobic compounds. C18 together with other alkyl phases such as C8 and C4 represent quite possibly the most basic form of reve

In many conditions, baseline separation of the peaks is usually obtained only with gradient elution and very low column loadings. Thus, two drawbacks to elution manner chromatography, Particularly on the preparative scale, are operational complexity, on account of gradient solvent pumping, and reduced throughput, due to low column loadings. Displac
