Waters Corp Waters Column, RP/Anion-exchange, 1.7 μm, 2.1 x 100 mm
This column excels at retaining polar acidic analytes in reversed-phase conditions. Its stable reversed-phase/anion-exchange mixed-mode chemistry, effective from pH 2–10, offers unique selectivity compared to traditional C18 phases for method development. The VanGuard FIT Column format is an all-in-one guard-column designed to reduce dead volume and extend column lifetime by filtering impurities.
- Excellent retention for polar acidic analytes under reversed phase conditions.
- Stable reversed phase/anion-exchange mixed mode chemistry from pH 2–10 for method development.
- All-in-one guard-column design reduces dead volume and increases column lifetime.
- Removes chemical impurities and suspended solids, enhancing column reliability.
- Tolerates pressures up to 15000 psi (1030 bar) in UPLC System applications.
Waters Corp Waters Spherisorb Amino (NH2) Guard Cartridge, 80 Å, 5 μm, 4.6 mm x 10 mm, 3 pk
These Amino (NH2) guard cartridges feature a silica-based aminopropyl bonded sorbent and are classified as USP L8. They are suitable for anion-exchange, normal-phase, and HILIC separations. Designed to protect analytical columns, these cartridges extend lifespan by preventing suspended particles and chemical contaminants from reaching the analytical column. The NH2 (Amino) packing has an intermediate ligand density and a 2.0 percent prescribed carbon load.
- Utilizes same high-performance packing materials as analytical columns for long-lasting performance.
- Developed for applications requiring higher capacity for biological fluid purification or temperature control.
- Manufactured in a cGMP, ISO 9001-certified facility using ultra-pure reagents.
- Each batch is chromatographically tested with neutral, acidic, and basic analytes for consistent, reproducible performance.
Waters Corp ACQUITY UPLC VanGuard Pre-column, Amide, 300Å, 1.7 μm, 2.1 mm × 5 mm
These columns analyze intact glycoproteins, fragments, and glycopeptides. Each batch undergoes quality control with a performance test standard, including Ribonuclease A and B glycoforms, ensuring batch-to-batch consistency. The kit contains one column and a vial of the standard for immediate benchmarking. The standard can be reordered for continuous monitoring, with each batch prepared under strict quality control, confirmed by a certificate of analysis.
