Agilent DB-5 30m, 0.25mm, 0.10u 122-5031

The Agilent DB-5 (catalog 122-5031) is a 30 m fused‑silica capillary gas chromatography column with a 0.25 mm inner diameter and 0.10 µm DB-5 stationary phase (5% phenyl‑methylpolysiloxane). Manufactured for general‑purpose GC separations, it provides a nonpolar, low‑bleed phase and a high temperature limit for routine analyses and compatibility with Agilent GC systems. The column is intended for separating a wide range of volatile and semi‑volatile organic compounds and can be used in both routine GC and GC‑MS workflows where low bleed and thermal stability are required.

Key Features:

• Length: 30 m
• Inner Diameter (ID): 0.25 mm
• Film Thickness: 0.10 µm
• Phase: DB-5 (5% phenyl‑methylpolysiloxane)
• Format: 7‑inch cage
• Capillary tubing: fused silica
• Temperature range: −60 °C to 325/350 °C

Advantages:

• Nonpolar, general‑purpose DB‑5 phase suitable for a wide range of analytes.
• Low column bleed improves sensitivity and makes the column suitable for GC‑MS work.
• High temperature limit supports analysis of higher‑boiling compounds and demanding methods.
• Bonded, crosslinked and solvent‑rinsible construction enhances durability and allows cleaning.
