WebMay 29, 2024 · Eluent strength (•°): a measure of the solvent adsorption energy.Eluotropic series: ranks solvents by their abilities to displace solutes from a given adsorbent. In adsorption chromatography, the more polar the solvent, the greater is its eluent strength, the more rapid will solutes be eluted from the column. The process is similar to paper chromatography with the advantage of faster runs, better separations, and the choice between different stationary phases. Because of its simplicity and speed, TLC is often used for monitoring chemical reactions and for the qualitative analysis of reaction products. Plates can be labeled before or after the chromatography process using a pencil or other im…
