WebAbstract. Reversed-phase high-performance liquid chromatography (RP-HPLC) involves the separation of molecules on the basis of hydrophobicity. The separation depends on the hydrophobic binding of the solute molecule from the mobile phase to the immobilized hydrophobic ligands attached to the stationary phase, i.e., the sorbent. Web8 de nov. de 2024 · HPLC – liquid chromatography performs separations. Chromatography originally started out as a technique performed at atmospheric pressure and relying on gravity – but as technology progressed it was found that using higher pressures – nowadays we use pressures between 50 and 300 bar - allowed faster and better separations. duke university frenchWeb29 de mai. de 2024 · How Does A Degasser Work In HPLC?
