Best Grade Chromatography Media Adsorbents

1. Best Grade Chromatography Media Adsorbents In all types of chromatographic techniques, what remains of prominent importance to carry out the process successfully and to obtain desired results is the selection of adsorbent “the stationary phase”. The most common adsorbents used in chromatography are Alumina (Al2O3) and Silica gel (SiO2), they also happen to be the widely used adsorbents as they work well across a wide range of compounds. The stationary phase is generally referred to as chromatographic media in modern chromatographic separations. It is either packed in a chromatography column or added to the separation apparatus. The media is always chosen depending on the type of molecule that is to be separated. The choice of mesh size differs on various parameters such as the complexity of the mixture of compounds, the amount of water present in it, and the chemical nature of the compound in question. Generally, an adsorbent with a higher mesh size is used for those chromatographic methods in which the solvent uses positive air pressure to run through the column and a smaller mesh size is used for those, where the solvent runs down the column on its own due to gravity. These are the features that signify the quality of silica gel and assure one of the desired results including reproducibility. Aluminium oxide as an adsorbent provides reproducible results hence they are widely used for carrying out the separation and purification of dyes, organic solvents, alkaloids, steroids, lipids, amino acids, hormones, and vitamins.
