any help or suggestions for a 1-2 page lab report on this???
Thin Layer and Paper Chromatography hromatography is a method of separation of compounds based on the principle of phase distribution. There are several different kinds of chro matography: thin layer, gas, paper, column and liquid chromatography are among the most common types used in organic chemistry. All methods of chromatography involve the partitioning of a substance between a stationary phase and a mobile phase. In paper chromatography the paper itself serves Background and Theory as the stationary phase and the eluting sol as the mobil phase. In layer chromatography the stationary phase is the silica gel layer, a plastic or glass plate scrves as a support, while again the eluting solvent functions as a mobile phase. The stationary phase adsorbs compounds by molecular interactions between functional groups on the stationary phase and the analyte compound. The commonly used stationary phases are polar. Thus, in this type of chroma- tography polar compounds are held more strongly by the stationary phase. Therefore, in order to elute increasingly polar compounds a mobile phase of greater polarity is needed. This property defines an eluatropic series. It begins with nonpolar solvents and proceeds gradually to the mostp organic solvent, methanol and finally water. The ability of a solvent to elute a given substrate from a stationary phase depends on the solvents eluting power and thus its polarity olar
