Note: I'm taking a simple view of the way that thin layer chromatography works in terms of adsorption (see below) which should be adequate for students doing courses for 16 - 18 year olds.The reality is more complicated and the explanation will vary depending on what sort of solvent or solvent mixture you are using. Some similar problems are discussed on the page …

TLC, one phase is a mobile liquid solvent phase and the other phase is a stationary solid phase with a high surface area. The stationary phase normally consists of a finely divided adsorbent, silica (SiO 2) or alumina (Al 2O 3) powder, used in the form of a thin layer (about 0.25 mm thick) on a supporting material.

Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al 2 O 3 catalysts. It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature.
