An '''eluotropic series''' is listing of various compounds in order of eluting power for a given [[adsorbent]]. The “eluting power” of a [[solvent]] is largely a measure of how well the solvent can "pull" an [[analyte]] off the adsorbent to which it is attached. This often happens when the [[eluent]] adsorbs onto the stationary phase, displacing the analyte. Such series are useful for determining necessary solvents needed for [[chromatography]] of chemical compounds. Normally such a series progresses from non-polar solvents, such as [[n-hexane]], to polar solvents such as [[methanol]] or [[water]]. The order of solvents in an eluotropic series depends both on the [[Stationary phase (chemistry)|stationary phase]] as well as on the compound used to determine the order.
