The invention is based on the immobilization of the ligatenthrough coordinationnbonding to a support material activated by hydroxidesnmetals forming coordination bonds.nThe carrier material used is porousnglass, optionally glass plates or sticksnwith an acid-treated surfacenor alkaline, or simply treatednroughening, eg by grinding.nOwn free and bound separationn, the ligand is in the case of a small carriernparticles in the sedimentation of these particlesnligand-bound, in the case ofn- larger sizes in the mere removal of the nosenOf the plant material.nThe invention can be used for highnsensitive and specific analysis, peptides,nhormones, vitamins, steroids, alkaloids,npesticides, toxins and the like. |
