WebLike traditional chromatography, there are three components of a TLC system: the stationary phase, the mobile phase, and the solute. However, unlike traditional chromatography, the stationary phase is arranged in a thin layer on a plate rather than packed into a column. Web2 okt. 2024 · Typically the primary step is to detect a mobile phase that will transfer the component with an Rf value 0.5. In complicated separations, a mobile phase may be required with changing composition. Interaction forces involved in TLC comprise inductive forces, charge transfer, intermolecular forces, covalent bonding, and hydrogen bonding. step flashing and counter flashing
