Tlc More Polar Solvent at Tom Wildes blog

Tlc More Polar Solvent. Proper solvent selection is perhaps the most important aspect of tlc, and determining the best solvent may require a degree of trial and error. A sample of aspirin has an $r_f$ value of 0.20 when measured on a silica gel tlc plate with a certain solvent mixture. Tlc mobile phase (solvent system) the solvent dissolves the sample components from the sorbent layer and transports them across the plate. The more polar the compound then the stronger it binds to. In general, the adsorptivity of compounds increases with increased polarity (i.e. The first plate was run using a 6:1 hexane:ethyl acetate mixture, which means the. If the polarity of the solvent is increased, the $r_f$. It was mentioned before that the. Another run must be made using a more polar solvent to improve the separation. When a mobile phase is made more polar than originally, all compounds travel further and have a higher \(r_f\). Relationship between rf value and polarity of the sample. In case, a reduction of r f is required, a decrease. The more strongly the solvent is.
