Aluminium Oxide for Chromatography is a white to off white, fine-grained powder, highly porous form of aluminium oxide. Its surface is more polar than that of Silica Gel and reflecting the amphoteric of aluminium, has both acidic and basic characteristics.

The process steps of HPTLC are identical to classical TLC. The main difference between them is in the characteristics of the separation plate. HPTLC plates are based on optimized silica gel 60 with a significantly smaller particle size than used for classical TLC. This allows a higher packing density and a smoother surface.

Silica Gel and Alumina are both polar adsorbents but Silica Gel is less polar than Alumina. Carbon-carbon double bonds contribute somewhat more to compound adsorption on alumina as compared to silica gel, and hence compounds with unsaturation are generally better separated on Alumina than on other polar adsorbents such as silica gel.

Feb 06, 2020 · There are two sides to the TLC plate. A silica side and a glass side. The glass side is just smooth reflective glass, and the silica side is a powdery white substance that will flake off if you disturb it. So be careful when handling these plates so as to not ruin the silica gel. Touching the silica with your fingers should be avoided!
