Optimized for maximum efficiency, superior peak shape and resolution. Utilizes the same ultra high purity silica as all ACE phases.

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.

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.

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.

Increased bonding density compared to ACE C18. Similarly optimized for maximum efficiency, superior peak shape and resolution.

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.

Combines lower hydrophobicity with excellent chromatographic performance. Improved hydrolytic stability compared to conventional C4 phases.

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.
