The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they

    1-hexanol D-4 #1‚2 C=O‚ -CH Cannot conclude Preparative Gas Chromatography was used to separate volatile compounds‚ which can then be identified. The injected sample becomes vaporized and was carried through the mobile column. It is usually carried by an inert gas. The gases were moved through the stationary column. The polarity of the components to the column would cause the separation of the components. Opposite to a TLC‚ if the stationary column was very polar‚ the more polar components will fall behind
