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.

Application Column
Primesep B
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
