Stationary phase - The solid material that absorbs the mixture flowing through it., Mobile phase - The liquid that transports the substance mixture through the absorbing material which travels along the stationary phase or 'bed' and carries the substance components with it., Chromatography - A method used to separate chemical mixtures for analysis., Chromatogram - The resulting paper or plate produced showing the substance separation., Rf - Retention factor, How is Rf calculated? - Distance moved by solute divided by distance moved by solvent, Qualitative - Data representing information that is not represented by numbers, Quantitative - Relating to, measuring, or measured by the quantity of something, Affinity - Components with higher affinity for the stationary phase move slower, while those with lower affinity move faster, Eluent - The solvent used in chromatography, often called the mobile phase., Solvent front - The distance the solvent moves on a chromatogram - used to measure Rf., Pencil is used to mark the sample line because... - it is insoluble in the mobile phase - pens may be soluble in the mobile phase and therefore interfere with results.,
