Abstract: The invention concerns a gel product for chromatography based on agarose, and a method of using the product for hydrophobe salting out adsorption. The gel product is characterized in that the hydrophobe groups are bonded to the agarose with ether or esther binding, and that the hydrophobe groups can be composed of aliphatic hydrocarbons, halogen or hydroxy-substituted alkyl groups, with 1 to 20 carbon atoms, or contain 1 or more, up to 5, aromatic nuclei, unsubstituted or substituted with alkyl, alkyloxy, halogen or NO.sub.2 or have the formula ##EQU1## where R can be alkyl, alkenyl, aryl, aralkyl, aralkoxy, alkaryl, optionally substituted with hydroxy, halogen or nitro, and where the alkyl parts of R contain 1 to 20 carbon atoms.
