Supelco® Introduces Ascentis® Express HILIC HPLC Columns for High-Speed and High-Efficiency Separations
The enabling technology for Ascentis Express is the Fused-Core™ particle. These high-purity silica particles measure 2.7 microns overall with a 0.5 micron-thick porous shell. Relative to columns using conventional sub-2-micron particles, Ascentis Express columns generate comparable efficiencies but with half the backpressure.

Features of Ascentis Express
There are five key user benefits with the Ascentis Express HPLC Columns:
1. Hyper-Fast Separations
Designed for high flow rates and sample throughput, especially LC-MS* Half of the backpressure of sub-2-µm particles
2. High-Definition Resolution* Twice the efficiency of 3 µm particles* Longer columns permit doubling the plates over sub-2-µm particles* Shortest analyte diffusion path
3. Super-Sensitive* Sharper peaks provide better Signal:Noise
4. Super-Rugged* Narrowest particle size distribution* 2µm porosity frits like most rugged conventional columns
5. A Family of selectivities that rivals the competition* C18, RP-Amide, Phenyl-Hexyl, C8, HILIC* Match competitor selectivitiy and performance at lower pressure
