Witryna22 gru 2024 · If a highly aqueous mobile phase is necessary, 0.05% sodium azide can be added to the eluent. Alternatively, regular flushing of the HPLC system with organic solvent, preferably isopropanol or methanol, prior to standby, is mandatory. Do not use acetonitrile, because acetonitrile can polymerise and block system valves. Conclusion WitrynaThis liquid, or the eluent, is the mobile phase, and it slowly rises up the TLC plate by capillary action. As the solvent moves past the spot that was applied, an equilibrium is established for each component of the mixture between the molecules of that component which are adsorbed on the solid and the molecules which are in solution. WitrynaHere, silica acts as the stationary phase and the solvent in which the plate is dipped and that runs up the plate by capillary action is the mobile phase.
