ACE SuperC8 Ultra-Inert UHPLC and HPLC s with Extended ph Stability Encapsulated Bonding Technology (EBT ) for Improved Chromatography and Stability Traditional C8 Bonding ACE SuperC8 with Encapsulated Bonding Technology (EBT ) C8 Endcapping group Unbonded silanol group C8 The unique Encapsulated Bonding Technology (EBT ) developed for ACE SuperC8 columns dramatically increases ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups from separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Under aggressive acidic conditions (see Figure ) ACE SuperC8 is highly resistant to ligand cleavage, due to a combination of the Encapsulated Bonding Technology (EBT ) and ultra-inert ACE silica. Many C8 bonded columns will exhibit ligand cleavage under acidic conditions, resulting in retention shifts and/or increased peak tailing. Under basic conditions with LC/MS compatible mobile phases (see Figure ), the Encapsulated Bonding Technology (EBT ) shields the ACE SuperC8 surface from dissolution whilst maintaining excellent chromatographic performance. Traditional C8 bonded silica columns are prone to silica dissolution under such aggressive conditions, which can result in premature column deterioration.

Please see page for acknowledgement of trademarks. Conclusion: Significant differences in efficiency, peak shape and selectivity are seen when analysing pyridine a basic molecule. Increased tailing and retention, combined with reduced efficiency, are indicative of undesirable secondary interactions between pyridine and silanol groups on the stationary phase surface. These interactions can also result in poor column reproducibility. ACE C8 columns have gained a well deserved reputation for providing excellent efficiency, peak shape and reproducibility. ACE SuperC8 columns further build upon this proven reputation to provide the analyst with even better chromatographic performance across an extended range of ph conditions under LC/MS compatible conditions.

Please see page for acknowledgment of trademarks. Conclusion: When analysing a basic molecule (pyridine) at high ph, differences in efficiency, peak tailing and retention are seen. This suggests undesirable secondary interactions between the basic molecule and silanol groups on the stationary phase surface remain. Further to the intermediate ph comparison (see page ), the ACE SuperC8 again provides excellent peak shape and efficiency when analysing a basic molecule (pyridine) at high ph, indicating undesirable secondary interactions have been virtually eliminated. These undesirable interactions can also result in poor column reproducibility. Changing ph is a powerful tool to enable the selectivity to be optimised and sample impurities to be identified. ACE SuperC8 columns are designed to provide excellent peak shape and lifetime under acidic, intermediate and high ph with LC/MS compatible buffers, and may additionally be used with mobile phases containing MeOH or MeCN without suffering efficiency loss and/or extended equilibration times.
