The 2 phases of chromatography
Web28 Nov 2024 · Chromatography consists of two phases: one mobile phase and one contiguous stationery phase. The stationery phase is liquid or solid and the mobile gas is gas or liquid. What is the stationary phase in TLC? Thin Layer chromatography (TLC) is an analytical technique used to separate a mixture into its components. The stationary phase … WebPhases Chromatography relies on two different ‘phases’: the stationary phase is paper, or a thin layer of powder coated onto a glass or plastic plate the mobile phase is a solvent that...
