Product Description
The Ascentis Express HILICGuard cartridges 5x4.6mm, 5µm, are used for column protection of Ascentis Express HILICHPLC and UHPLC columns with an internal diameter of 4.6mm. The Ascentis Express Guard Cartridge Holder 53500-U serves as the housing.
Features and Benefits
- Fused-Core particle technology
- High efficiency at moderate pressure
- Wide range of RP, HILIC, and specialty selectivities
- Suitable for HPLC and UHPLC
- Directly compatible guard cartridge column protection
Additional Notes
Ascentis Express columns are based on fused-core or superficially porous particles. A solid core combined with a porous shell provides short diffusion paths and an efficient packing structure. As a result, high column numbers and narrow peaks can be achieved, often without reaching the backpressure associated with fully porous sub-2-µm particles. The platform includes classic reverse-phase columns, polar embedded phases, HILIC phases, and application-specific surface chemistries.
