The Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules therefore, geometric and positional isomers of conjugated double-bonding systems are recognized and resolved.

• These columns is much more hydrophobic and lipophilic
• Even when pure organic eluents are applied, many sample solutes are retained
• Applicable for LC-MS

Carotenoids are found in a variety of natural sources including fruits and vegetables. In addition, carotenoids are considered as potential drugs for cancer intervention and/or prevention. Despite the complexity of carotenoid extracts and the minor shape differences between carotenoid isomers, the separation, identification, and quantitation of these compounds can be achieved using these columns.
