WebJun 6, 2024 · Since the adsorbents are polar, the more polar compounds are adsorbed more strongly. Thus, non-polar compounds are eluted first. Why do polar molecules elute first? So as polar molecules are retained in the column, your elution of molecules will go from non-polar to polar. For reversed-phase chromatography things are, well, the reverse. WebThe ferrocene elutes from the column first because it is less polar than the acetlyferrocene and is thus more attracted to the relatively non-polar mobile phase compared to the polar stationary phase.
