Agilent UHPLC Guard, SB-C8, 2.1mm, 1.8um, 3pk 821725-904

ZORBAX RRHD StableBond C8 UHPLC Guard columns, 2.1 mm ID, 1.8 µm particle size, are guard cartridges designed to protect analytical columns from particulates while preserving chromatographic performance. They are intended for use on low-dispersion UHPLC and UHPLC systems to extend column life and maintain system efficiency in reversed-phase separations.

Key Features:

• Phase: SB-C8 (ZORBAX StableBond)
• Particle size: 1.8 µm (fully porous)
• Inner diameter: 2.1 mm; Length: 5 mm
• Pore size: 80 Å
• Pressure rating: 1200 bar
• pH range: 1–8
• Maximum temperature: 40 °C at pH 6–8; 80 °C at pH 1–6

Advantages:

• Protects analytical columns from particulates without compromising chromatographic performance.
• Extends column lifetime and helps maintain system efficiency on UHPLC platforms.
• StableBond silica chemistry provides robustness for low-pH reversed-phase method conditions.
• High pressure rating (1200 bar) and small particle size (1.8 µm) support high-efficiency UHPLC separations.
