The Agilent ZORBAX Eclipse Plus C18 guard cartridge (catalog 821125-936) is a 2.1 x 12.5 mm, 5 µm guard cartridge designed for HPLC reversed‑phase workflows. It is used as a replaceable guard to protect analytical Eclipse Plus C18 columns, capture particulates and strongly retained matrix components, and help extend column lifetime during routine method development and sample analysis.
Key Features:
- Phase: Eclipse Plus C18 (reversed phase).
- Dimensions: 2.1 mm ID × 12.5 mm length (guard cartridge).
- Particle size: 5 µm, fully porous.
- Pore size: 95 Å; Carbon load ~9%; double endcapped.
- Operational limits: pH range 2–9; max temp 60 °C (pH 2–6) / 40 °C (pH 6–9); pressure rating ~400 bar.
Advantages:
- Protects and extends the life of analytical Eclipse Plus C18 columns by capturing contaminants and particulates (guard cartridge function).
- Broad pH compatibility (2–9) and rated temperatures support method development across common reversed‑phase conditions.
- Double endcapping and ~9% carbon load reduce secondary interactions for more reproducible retention and peak shape.
- Sold as a 4‑pack replacement cartridge set for routine maintenance and convenient column protection scheduling.
