3) Obtain a chromatography chamber (a beaker covered with a watch glass or aluminum foil) and add developing solvent (a mixture of petroleum ether and acetone). The solvent should completely cover the bottom of the chamber to a depth of approximately 0.5 cm. 4) Obtain chromatography paper. Make sure that it fits into your beaker.Plant Pigment Chromatography - Lakewood High School 1. Pour 10 mL of chromatography solvent into a 100 mL graduated cylinder. Cover the cylinder with aluminum foil. 2. Cut the end of the chromatography paper into a point. 3. Draw a pencil line 2.0 cm above the pointed end of the paper. 4. Use the coin to extract pigments from the spinach leaf. Place a small amount of . the leaf on top of the pencil line.Thin Layer Chromatography (TLC) - Boston College Place a piece of aluminum foil over the mouth of the beaker. Allow the chromatogram to develop undisturbed for 60 to 75 minutes. Do not move the beaker while the chromatogram is developing! When you remove the paper from the beaker, mark the solvent front with a pencil. Set the cylinder on notebook paper, and allow it to dry.

Alumina Al2O3 - PubChem

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore.Aluminum Foil VWR Aluminum Foil.

It overcomes the relatively low and high pH instability of silica. Alumina is stable throughout the pH range of 2-13. This is a most important feature. When silica is used in a chromatography column at higher pH, one always gets column collapse associated directly with silica dissolution.
