Selectivity and Separation for Isomers
Compared to classical C18 stationary phases, YMC Carotenoid C30 is much more hydrophobic. Even when pure organic eluents are applied, many sample solutes are retained. The YMC 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. The C30 resolving power for isomers can be verified by the separation of carotenoids, which has been the subject of considerable research efforts in the past. 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 YMC Carotenoid C30 columns.
YMC’s Guard Column Cartridge Systems for Semi-Prep HPLC utilize cartridges of 10, 20, or 30mm inner diameters – in 10mm lengths. Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column (including columns by other manufacturers). Assembly is tool-free, simplifying cartridge replacement.
YMC Guard Column Cartridges require the use of a holder, P/N: XPCHSPW1 for 10mm I.D., P/N: XPCHSPW2 for 20mm I.D. and P/N: XPCHSPW3 for 30mm I.D.
