ACE C18
Optimized for maximum efficiency, superior peak shape and resolution. Utilizes the same ultra high purity silica as all ACE phases.
ACE C18 HL
Similar to ACE C18 in selectivity, but with higher loadability. Useful for preparative applications.
ACE C18-AR >
Leverages the selectivity of both C18 and Phenyl in a single phase to separate mixtures not possible with either a C18 or Phenyl phase alone. Complementary selectivity to ACE C18 and ACE C18-PFP. Compatible with highly aqueous mobile phases.
ACE C18-PFP >
Offers multiple types of analyte-stationary phase interactions (hydrophobic, π–π, dipole-dipole, and hydrogen bonding) to deliver optimal selectivity for a variety of mixtures. Complementary selectivity to ACE C18 and ACE C18-AR. Compatible with highly aqueous mobile phases.
ACE AQ (C18)
A unique C18 bonded phase with integral polar functionality. Resistant to retention loss (due to pore dewetting, formerly called “phase collapse”) even with 100% aqueous mobile phases.
ACE C8
Increased bonding density compared to ACE C18. Similarly optimized for maximum efficiency, superior peak shape and resolution.
ACE Phenyl
Hydrophobicity between C4 and C8 phases, with increased polar selectivity. Improved performance, stability and reproducibility compared to conventional phenyl phases. Compatible with highly aqueous mobile phases.
ACE C4
Combines lower hydrophobicity with excellent chromatographic performance. Improved hydrolytic stability compared to conventional C4 phases.
ACE CN
Suitable for use in both normal and reversed-phase modes. Provides strong dipole-dipole interaction with analytes and weak hydrophobic interaction. Greatly improved performance, stability and reproducibility compared to conventional CN phases.
