Proceture column chromatography
1. To measure the adsorbent, fill the column one-half to two-thirds full, and then pour the powder into 50 ml beaker
2. Fill the column with hexanes to the top of the glass column
3. Add hexanes to the adsorbent in the beaker stir the mixture to eliminate air bubbles, and then swirl the mixture to gen the adsorbent suspended in the solvent and immediately pour the entire slurry into column through the funnel
4. Carefull add the lycopene sample to the prepared column
5. Fill the column with the solvent and elute the sample from the column
6. Collect the yellow carotene band eluted by ligroin or hexanes
