Product Description
The InertSustain AQ-C18 pre-columns 25x4.0mm, 5µm, are used to protect InertSustain AQ-C18 HPLC columns with an inner diameter of 4.0mm. Since these are packed precolumns, no holder is required.
Performance Characteristics and Advantages
- Specially modified silica for high pH values
- Very low backpressure
- High inertness toward all analytes (base-deactivated)
- High efficiency
- Compatible with many solvents
Additional Notes
The InertSustain series features a specially modified silica. This allows for precise control of the properties of the silica matrix. In addition, the columns exhibit high pH stability. As with the established Inertsil series, the InertSustain materials also demonstrate very high inertness toward all analytes—a phenomenon also referred to as base deactivation. Furthermore, these materials exhibit very low backpressure while maintaining high efficiencies. The service life can be extended by using appropriate pre-column cartridges.
