YMC-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 significantly shorter retention for non-polar compounds. Retention of polar compounds, however, is not significantly affected. Therefore, mixtures with a wide range of component polarity are best analyzed by YMC Butyl. This is because the butyl bonded phase gives shorter analysis times while still maintaining high resolution when compared to longer chain bonded chemistries.
Application: For 2,4-Dinitrophenylhydrazones of Aldehydes and Ketones
- Ideally suited for biological separations
- High coverage monomeric bonding on perfectly spherical silica supports
- Fully endcapped
