HPLC Separation of Vitamin E and Vitamin E Acetate on Primesep B Column

Primesep B separates Vitamin E and Vitamin E acetate with reversed peak order of a traditional C8 column. The different selectivity is due to an embedded basic functional group on the stationary phase which contributes polar interactions to the separation. Excellent peak shape results with a mass spec compatible mobile phase of water and acetonitrile (MeCN, ACN) with UV detection at 205 nm.
