PH12S11-0551DRGPhenyl columns provide unique selectivity when compared to aliphatic straight chain reversed phases such as ODS, C8 and C4. The p electrons of the phenyl group can interact with the aromatic ring of an analyte to increase retention relative to -
OC12S11-0551DRGThe hydrophobicity of YMC-Pack C8 is moderate for a reversed-phase packing material. Retention times of samples on YMC-Pack C8 tend to be shorter than those on ODS stationary phase. -
BU30S11-0551DRGThe YMC-Pack C4 stationary phase surface hydrophobicity is lower than that of both ODS and C8 Retention times of samples on YMC-Pack C4 therefore tend to be shorter than those on ODS or C8. Separation characteristics of YMC-Pack C4 also differ from -
BU20S11-0551DRGYMC-Pack C4 (Butyl) columns are less hydrophobic than C8 or C18 packings, and generally utilize more aqueous eluents than either of these reversed phase column types. When compared to C8 and C18 columns using the same eluent, C4 columns show -
SL06S11-0551DRGThe high purity silica found in YMC-Pack Silica columns provides virtually complete sample recovery. The absence of silica impurities reduces non-specific sample adsorption which lowers sample recovery and may cause unusual peak shapes.
