Aluminium oxide ( alumina ) as binder is by far the most extensively used adsorbent in Thin Layer Chromatography because of the excellent separation it affords. When coated on a plate in the form of thin layer it serves as a versatile solid stationary phase for adsorption and partition chromatography.
Aluminium oxide ( Alumina ) ā `Gā can be successfully employed in both qualitative and quantitative analysis of alkaloids, amino acids, oils and fats, vitamins, plant pigments, drugs and sugars.
