Phase design:
- ACE Excel CN-ES combines a polar terminal CN group with an extended spacer.
- ACE Excel CN-ES extended spacer technology additionally provides increased column lifetime compared to traditional CN bonded phases with short alkyl spacer.
The unique design of the ACE CN-ES incorporates an Extended Spacer alkyl chain between the silica surface and CN group that gives extra phase stability in mobile phase eluents (pH 2 - pH 8). The extended spacer also provides enhanced hydrophobicity to the phase.
