Carotenoids is a broad class of natural products, so far, over 600 kinds of carotenoids has been found, including different length of carbon chain compounds such as C40, C50 and C30 etc. It is well known as many biological functions, including cancer prevention and treatment function. Compared to classical C18 stationary phases, C30 is much more hydrophobic and retainable. Even when pure organic eluent is applied, many sample solutes, for example carotenoids, are able to retain. Ultisil C30 is designed for the separation of geometric isomer recognition, polar carotenes, polar and nonpolar xanthophylls, steroids, retinols and fat-soluble vitamins (A, D, K and E)

Characteristics of C30:

• Polymeric C30 alkyl chains
• Very lipophilic
• Exceptional selectivity pattern for geometric izomers
