Waters Corp Waters Corporation VanGuard Pre-column, BEH Amide, 1.7 μm
Supplier: Waters Corp 186004799
This VanGuard pre-column utilizes BEH technology with a chemically stable, trifunctionally bonded amide phase, allowing for the retention and separation of extremely polar compounds across a wide pH range (2 to 12). It connects directly to the UPLC column inlet, minimizing extra column volumes and leaks.
- Protects column from contamination.
- Reduces peak tailing and improves resolution.
- Extends analytical column lifetime.
- Retains polar analytes poorly retained by reversed-phase chromatography.
- Facilitates mobile phase use from pH 2–11.
- Increases chemical stability for high pH and temperature applications.
- Prevents Schiff base formation, enhancing quantitation.
- Increases mass spectrometry response, simplifying sample pre-treatment.
- Enables high resolution and high-speed analysis with 1.7 μm particle size.
