one. Typical section chromatography: Here the stationary section from the column is made from polar compounds like silica gel, alumina, etcetera. When the procedure is run, the nonpolar compounds are eluted initially. The polar compounds while in the sample have bigger affinity to your stationary phase, and so they are retained for a longer period
