Agilent ZORBAX Eclipse XDB-C18 guard cartridges (part number 820950-925) are 4.6 x 12.5 mm, 5 µm guard cartridges sold as a 4/pack for HPLC systems. They serve as short guard columns (ZGC cartridges) placed ahead of analytical columns to trap particulates and contaminants, extending column life and maintaining system efficiency. The Eclipse XDB-C18 phase is eXtra densely bonded and double end‑capped to minimize active silanols, making it suitable for reversed‑phase separations and improved peak shape.
Key Features:
