Reversed-phase liquid chromatographic (RPLC) separation of isomers and homologues of similar polarity is challenging. Tocopherol isomers and homologues are one such example. α, β, γ, and δ-tocopherols have been successfully separated by RPLC on triacontyl (C30) stationary phase. System suitability was tested by using four mobile phases, and observed chromatographic separations of β and γ-tocopherols...
