InertSustain AQ-C18 LC Columns
- Exceptional retention for highly polar compounds (hydrophilic)
- Highly inert packing material results in less tailing of peaks
- Extreme resistance to low and high pH mobile phases
- Endlessly reproducible from column-to-column and batch-to-batch
- Rapid gradient re-equilibration
InertSustain AQ-C18 columns are designed to achieve strong retention for highly polar compounds, which is the most challenging goals in developing reversed phase methods. The optimization of bonding of the C18 groups at equal distance to the silica gel enable InertSustain AQ-C18 to offer significant retention for highly polar compounds even under water rich mobile phases.
Recommended for applications where 100% aqueous mobile phases are required. Ideal for fast gradients due to rapid re-equilibration properties.
Highly Polar Compound Retention with 100% Aqueous Mobile Phases
It is indeed difficult to retain highly polar samples by reversed phase mode as the polar samples tend to elute near the t0 with water rich mobile phases. On the other hand, polar embedded C18 columns or C18 columns with hydrophilic endcapping are available in the market for retaining highly polar compounds. However, they often show tailing or poor peak shapes due to the secondary interaction from their embedded functional groups. InertSustain AQ-C18 not only provide strong retention for highly polar compounds, but also delivery symmetric peak shapes for virtually any type of analytes.
The AQ column is avaiable in Metal, PEEK, Preparative, Capillary and Steel-Coated PEEK. The InertSustain AQ HPLC Column is both for UPLC and HPLC.
