  Separation of tocopherols on (a) C18-mono, (b) C18-poly, (c) C30,  and (d) Sil-FIP phases

• Associated context:

  Comparative chromatograms for the separation of b- and g-isomers of tocopherol with C18-mono, C18-poly, C30, and Sil-  FIP are shown in Fig. 2. It is clear that Sil-FIP can separate b- and g-isomers, while other phases cannot separate the isomers at all.  The other isomers (a and d) are excluded here because their separation is not difficult due to the hydrophobicity differences.
