Avantor ACE HILIC UHPLC and HPLC columns are manufactured with 100 Å Ultra-Inert Base Deactivated Silica specifically designed for your HILIC method development needs. Avantor ACE HILIC UHPLC and HPLC columns are available in 3 different bonded phases HILIC-A (acidic phase), HILIC-B (basic phase), and HILIC-N (neutral phase). Avantor ACE HILIC UHPLC and HPLC columns are available in 1.7, 3, and 5 um particle sizes in all analytical column sizes. All Avantor ACE HILIC columns are known for their excellent peak shape and batch to batch reproducibility. Columns are packed in 1000 bar UHPLC hardware.
Waters Corp WATERS CORPORATION Sentry Guard Cartridge, C18, 5 μm, 4.6 mm, 20 mm
XSelect CSH C18 columns function as general-purpose columns, offering alternative selectivity compared to other C18 sorbents. The Charged Surface Hybrid (CSH) technology addresses common column-related issues such as peak shape asymmetry, poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.

Waters Corporation VanGuard Pre-column, BEH Amide, 1.7 μm
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.
