How does eluent strength affect elution in chromatography?

• Eluent strength describes the ability of the mobile phase to displace analytes from the stationary phase surface.
• A stronger eluent reduces analyte retention by increasing competition for stationary phase interaction sites.
• Differences in eluent strength change the order and speed at which analytes exit the chromatographic system.
