Comparison of leading C18 HPLC column brands

•  Significant differences in efficiency, peak shape and selectivity are seen when analyzing pyridine - a small highly basic molecule.

• Increased tailing and retention are generally indicative of undesirable secondary interactions between pyridine and silanol groups on the stationary phase surface.  These interactions can also result in poor column reproducibility.
• ACE Generix columns provide excellent separations at a lower cost than many leading HPLC column brands.
