Agilent Eclipse XDB-C18 Rapid Res 3.5um,4.6x30mm 933975-902

The Agilent Eclipse XDB-C18 Rapid Res 3.5 µm, 4.6 x 30 mm (933975-902) is a cartridge-format reversed‑phase HPLC column packed with Eclipse XDB‑C18 stationary phase designed for rapid‑resolution analytical separations. It is intended for high‑speed, routine reversed‑phase analyses where short run times and good peak shape are required, and it is compatible with cartridge hardware and standard HPLC systems. Manufacturer specifications identify it as a fully porous, USP L1 C18 phase with 3.5 µm particles and an 80 Å pore size for small‑molecule separations.

Key Features:

• Format: Rapid Resolution cartridge, 4.6 mm ID × 30 mm length
• Phase: Eclipse XDB‑C18 (USP L1)
• Particle size: 3.5 µm (fully porous)
• Pore size: 80 Å
• Pressure rating: 400 bar
• Useful pH range: 2–9

Advantages:

• Short 30 mm length with 3.5 µm packing enables fast, high‑throughput reversed‑phase analyses.
• Eclipse XDB C18 chemistry (dense bonding and double endcapping) reduces active silanol effects for improved peak shape, especially for basic compounds.
• Cartridge format simplifies installation and replacement for routine workflows.
• 400 bar rating and a broad pH range (2–9) provide robustness and flexibility across common HPLC methods.
