Summary:FIELD: recovery of efficiency of chromatographic columns lost in the process of service. ^ SUBSTANCE: recovery of the full efficiency of columns for highly effective liquid chromatography is effected by treatment by carbon dioxide in a supercritical state. The column is treated at a pressure of 250 atm., temperature within 120 to 140 deg. ^ EFFECT: accelerated and reduced price of the recovery of the efficiency of columns without their disassembly. ^ 4 cl, 1 dwg, 3 ex
