Agilent DB-5 30m, 0.25mm, 0.25u 122-5032

The Agilent DB-5 column (catalog 122-5032) is a 30 m fused‑silica capillary gas chromatography column with a DB‑5 (5% phenyl‑methylpolysiloxane) stationary phase, 0.25 mm inner diameter and 0.25 µm film thickness. It is intended for routine GC and GC/MS separations where a low‑polarity, thermally stable phase is required; Agilent specifies an operating range of −60 °C to 325/350 °C and lists suitability for ASTM methods.

Key Features:

• Length: 30 m.
• Inner diameter (ID): 0.25 mm.
• Film thickness: 0.25 µm.
• Phase: DB-5 (5% phenyl‑methylpolysiloxane).
• Capillary tubing: fused silica.
• Format: 7‑inch cage (standard capillary format).

Advantages:

• Low‑polarity DB‑5 phase provides broad applicability across volatile and semi‑volatile analytes, making it suitable for many routine GC and GC/MS methods.
• Manufacturer‑rated thermal range (−60 °C to ~325/350 °C) supports high‑temperature separations and reliable performance for thermally robust analyses.
• Standard 0.25 mm ID with 0.25 µm film offers a practical balance of chromatographic efficiency and sample capacity for routine analytical workflows.
• Supplied in a common 7‑inch cage format compatible with many Agilent and similarly sized non‑Agilent GC systems for straightforward installation.
