Uses of various adsorbents are common in almost all chromatography process. Generally, Silica gel and alumina are the 2 most widely used desiccants for chromatography. The basic activity of adsorbents is the separation of liquid and solid compounds.

I would like to know that the purpose of using desiccants for various chromatography i.e. Gas chromatography, Flash chromatography, thin layer chromatography are same or different for each and every individual chromatography?
