Adding cationic material to silicic acid sorbent chromatographic sheet for improved performance

Abstract

Abstract A CHROMATOGRAPHIC MEDIUM EXHIBITING THE HIGH RESOLUTION OF THIN LAYER CROMATOGRAPHY BUT SUBSTANTIALLY GREATER CHROMATOGRAPHIC CAPACITY TAKES THE FORM OF A SELF-SUPPORTING, FLEXIBLE SHEET STRUCTURE COMPRISING A MAJOR PROPORTION, OR ABOUT 50% TO 90% BY WEIGHT, OF A CHROMATOGRAPHIC ADSORBENT, SUCH AS SILICIC ACID, UNIFORMLY AND HOMOGENEOUSLY DISPERSED WITH A MINOR PROPORTION OF STRUCTURALLY STABILIZING INORGANIC FIBERS SUCH AS GLASS FIBERS DISPOSED IN A RANDOMLY ORIENTED NETWORK AND ABOUT 0.01% TO ABOUT 1.5% BY WEIGHT OF A CATIONIC MATERIAL SUCH AS CATIONIC STARCH.
