Stationary phases in liquid-solid chromatography are typically solid materials that interact with the analyte components through adsorption. These phases are crucial in separating the components of a mixture based on differences in their interaction with the stationary phase. The characteristics of a stationary phase include surface area, porosity, and the type of functional groups present. The surface area determines the amount of analyte that can be adsorbed, while porosity affects the diffusion of the analyte through the stationary phase. Functional groups on the stationary
