How Does Adsorption Chromatography Measure Surface Affinity?

Adsorption chromatography measures differences in surface affinity among compounds with similar structures. In adsorption chromatography, closely related molecules compete for the same active sites on the stationary phase. Small structural variations influence how strongly each compound binds to the solid surface. These binding differences change retention time as some molecules remain adsorbed longer than others. By comparing travel distances or peak times, analysts can quantify variations in surface affinity. Check it out importance of adsorption chromatography to learn more about the given topic.
