• Reversed-Phase Column Stands up to 100% Aqueous Mobile Phases
• Hydrophilic Endcap Provides High Retention of Polar Compounds
• Column Equilibrates Quickly with Difficult Aqueous Mobile Phases
• Base-Deactivated Packing Provides Symmetrical Peaks
Traditional reversed-phase C18 packings will experience phase collapse under highly
aqueous conditions (typically greater than 95% water) resulting in little, if any, retention for
most analytes. The Alltima™ AQ packing with its hydrophilic endcap overcomes this
problem, allowing better retention of polar compounds with mobile phases up to and
including 100% aqueous conditions.
The Alltima™ AQ base silica is deactivated to give you symmetrical peaks with acidic,
basic, and neutral compounds. Mobile phase modifiers such as triethylamine (TEA) are
generally not required to produce sharp, symmetrical peaks.
All Alltima™ AQ columns are warranted for 90 days from the date of purchase. If you
are not entirely satisfied with your purchase please call Customer Service for a replacement
or full refund.
