HPLC Guard Columns and Cartridges
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.
