| 1941 Bacharach & Robinson tr. Zechmeister & Cholnoky's Princ. & Pract. Chromatography ii. 75 The individual homogeneous portions of the column are coarsely broken up..and then immediately dropped into the eluent..and stirred round. 1942 H. H. Strain Chromatographic Adsorption Anal. v. 65 Eluants, as a rule, are chosen with the object of obtaining rapid and complete liberation of adsorbed compounds. 1966 E. Haslam Chem. Vegetable Tannins iv. 100 The tannin may then be isolated using acetone or methyl ethyl ketone as eluant. 1969 J. A. Dean Chem. Separation Methods iv. 68 Assuming a fixed flow rate for the eluent, the time..at which each component in the sample will emerge from the column depends on the individual partition coefficients. |
