METHOD OF PREPARING MODIFIED MACROPOROUS SILICA FOR CHROMATOGRAPHY OF BIOPOLYMERS Russian patent published in 1997 - IPC

Abstract RU 2080905 C1

FIELD: production OF chromatographic materials. SUBSTANCE: silica with pore diameter 6-400 nm treated with vinylmethylchlorosilabe in organic solvent medium is evacuated, activated with γ-radiation source, and treated with trifluorostyrene vapor. Resultant sorbent has reduced capability of nonspecific sorption of ribonucleic acids from aqueous solutions. EFFECT: increased selectivity of sorbent. 2 tbl
