PROCESS AND DEVICE FOR CHROMATOGRAPHY Russian patent published in 1998 - IPC

FIELD: fast high-efficiency separation and indication of multicomponent mixtures. SUBSTANCE: chromatographic process includes deposition of analyzed sample on layer of sorbent fixed on surface of cone on side of its base, bringing of layer of sorbent into contact with eluent and separation of mixture into components with simultaneous concentration. Then sample is transferred continuously or discretely on to layer of sorbent fixed on surface of another cone over its circumference on side of its vertex at some distance from it and repeat separation is accomplished. Device for chromatographic analysis includes two or more layers of sorbent fixed on surfaces of cones, means to deposit sample and means to feed eluent. Cones are installed as split pair having continuous or discrete contact between layers of sorbent. EFFECT: enhanced efficiency of process and device. 15 cl, 6 dwg
