👉 Cochromatography is a separation technique used in chromatography that involves two or more phases separated by a solvent. The first phase, known as the eluent, typically contains the solute to be separated from the solvent. The second phase, known as the mobile phase, is a liquid that is passed through the eluent and separates the components of the mixture. In cochromatography, the eluent is often a liquid or suspension that is used to coat the surface of the mobile phase
