English: Elution sequence of the trivalent lanthanides and actinides from a Dowex 50 cation‐exchange resin column at 87 °C, using ammonium α-hydroxyisobutyrate (ammonium α-HIB) as the eluant. The broken curve for element 103 (Lr) shows an estimate based on its predicted atomic radius, as its half-life is too short to confirm its position in the elution sequence.
