Agilent DB-5 25m, 0.25mm, 0.25u 122-5022

The Agilent DB-5 (catalog 122-5022) is a 25 m fused‑silica capillary GC column with a low‑polarity DB‑5 stationary phase (5% phenyl‑methylpolysiloxane). It is designed for general‑purpose gas chromatographic separations of volatile and semi‑volatile organic compounds, offering robust performance across routine analytical applications.

Key Features:

• Length: 25 m.
• Inner diameter (ID): 0.25 mm.
• Film thickness: 0.25 µm.
• Phase: DB‑5 (low polarity, 5% phenyl‑methylpolysiloxane).
• Capillary tubing: fused silica.
• Operating temperature range: −60 °C to 325/350 °C.

Advantages:

• Low‑polarity DB‑5 phase provides broad applicability for separating nonpolar to moderately polar analytes, making it a versatile choice for routine GC methods.
• 25 m × 0.25 mm × 0.25 µm dimensions offer a balance of chromatographic resolution and analysis speed suitable for many laboratory workflows.
• Fused‑silica construction and wide temperature range support robust performance and thermal stability for analyses up to about 325–350 °C.
• Manufacturer catalog listing and USP designations provide traceability and suitability for standardized analytical methods.
