Ascentis® Express ES-Cyano, HPLC Column, 2.7 µm particle size, L x I.D. 7.5 cm x 2.1 mm

The Ascentis Express ES-Cyano HPLC/UHPLC column 75x2.1mm, 2.7µm, bears a cyano modification on a fused-core matrix. The Ascentis Express ES-Cyano can be used in reversed-phase and normal-phase methods and displays moderate polarity with additional dipole selectivity. Applications of the Ascentis Express ES-Cyano include polar organic compounds, basic analytes, intermediates and methods that lie between classical RP and NP mechanisms.

Features and Benefits

• Fused-Core particle technology
• High efficiency at moderate pressure
• Wide range of RP, HILIC, and specialty selectivities
• Suitable for HPLC and UHPLC
• Directly compatible guard cartridge column protection

Additional Notes

Ascentis Express columns are based on fused-core or superficially porous particles. A solid core combined with a porous shell provides short diffusion paths and an efficient packing structure. As a result, high column numbers and narrow peaks can be achieved, often without reaching the backpressure associated with fully porous sub-2-µm particles. The platform includes classic reverse-phase columns, polar embedded phases, HILIC phases, and application-specific surface chemistries.
