This conduct is to some degree peculiar to standard section chromatography as it is ruled Virtually exclusively by an adsorptive system (i.e., analytes communicate with a stable surface area in lieu of Along with the solvated layer of a ligand hooked up for the sorbent surface area; see also reversed-stage HPLC underneath). Adsorption chromatography remains somewhat useful for structural isomer separations in both column and slender-layer chromatography formats on activated (dried) silica or alumina supports.[citation needed]
