Description

Separate polar compounds with improved speed and resolution using Thermo Scientific™ Accucore™ aQ C18 Polar Endcapped LC columns. Rugged 2.6μm solid-core particles enable fast, high-efficiency separations at low backpressures. The polar endcapped C18 stationary phase provides optimal retention of polar analytes and is fully compatible with 100% aqueous mobile phases. Robust bonding technology and automated packing procedures ensure excellent reproducibility and long column lifetimes.

Alternative Selectivity

• Polar endcapped C18 stationary phase provides optimum retention of polar analytes
• Accucore aQ Columns are compatible with highly aqueous mobile phases.
• Polar encapping allows use in 100% aqueous mobile phases without loss of performance or stability.

Fast Separations

• 2.6μm core-enhanced technology particles enable operation at high flow rates without generating excessive backpressures.

Excellent Peak Shapes for Enhanced Resolution and Sensitivity

• Solid-core 2.6μm particles and narrow particle size distribution reduce band broadening and improve separation efficiencies.
• High surface coverage of silica minimizes secondary interactions and peak tailing.

Low Backpressures

• Solid-core 2.6μm particles for less backpressure compared to UHPLC sub-2μm particles
• Compatible with conventional HPLC instrumentation and UHPLC platforms

Excellent Reproducibility and Robustness

• Advanced bonding technology
• Automated packing process
