When developing the chromatography paper, what chemical will you use to spray on the chromatography paper?




It depends on what you will use the chromatography paper for. Different testable substances will require different mediums. However, for a plain-simple chromatography without staining/substance identification, aluminium oxide (or silica) coated on a plate is used, however paper can also be used.
