ACE® preparative HPLC C18-HL columns provide great reproducibility and column lifetime. These columns are available in a wide range of particle sizes and dimensions from capillary to preparative.

• Ultra high purity base deactivated silica
• 5,10 and 15 μm particle sizes available
• Fully validated columns; high sample recovery
• Exceptional reproducibility
• Excellent efficiencies
• 100 and 300 Å pore sizes

For preparative HPLC, resolution and loadability are of the utmost importance. The greater the resolution, the higher the sample load and the faster pure compound is obtained. The ability to optimise resolution at the preparative scale means starting with high performance separations at the analytical scale. The same features that make ACE® ultra-inert base deactivated analytical columns the choice of method development chemists, also make them the ideal choice for scale-up and process methods.

ACE preparative HPLC columns offer the following benefits:
1. Loadability - high surface area and carbon load for maximum sample capacity
2. Selectivity - available in unbonded and 12 bonded phases, including ACE SuperC18 and all ACE 'extra selectivity' phases, to optimise resolution and maximise sample capacity
3. Rugged - reliable, long-term performance
4. Guaranteed reproducibility - complete column/batch validation as for ACE analytical columns
5. Guard cartridges - available for maximum column protection

ACE preparative HPLC columns are available in a wide range of column dimensions and particle sizes. For maximum loadability, choose 30 mm I.D
columns. Use a 50 mm length column with a 5 μm particle size to optimise the speed of your separation. To maximise resolution, choose a 250 mm length column with a 5 μm particle size.
