Agilent DB-5 15m, 0.25mm, 0.25u 122-5012

The Agilent DB-5 122-5012 is a fused‑silica capillary gas chromatography (GC) column using a DB‑5 stationary phase. The product is specified as 15 m length with a 0.25 mm inner diameter and a 0.25 µm film thickness, employing a low‑polarity 5% phenyl‑methylpolysiloxane coating. It is rated for an operating temperature range of −60 °C to 325/350 °C and is supplied in a 5‑inch cage format for routine GC separations requiring a low‑polarity phase.

Key Features:

• Phase: DB-5 (5% phenyl‑methylpolysiloxane).
• Length: 15 m.
• Inner diameter (ID): 0.25 mm.
• Film thickness: 0.25 µm.
• Capillary tubing: fused silica.
• Temperature range: −60 °C to 325/350 °C.
• Format: 5‑inch cage.

Advantages:

• Low‑polarity DB‑5 phase provides broad applicability for separating many volatile and semi‑volatile compounds.
• 0.25 mm ID combined with a 0.25 µm film offers a practical balance of chromatographic resolution and analysis speed for common GC methods.
• High maximum temperature rating (up to ~350 °C) supports temperature programming and analysis of higher‑boiling analytes.
• Fused‑silica capillary construction yields high efficiency and inertness for reproducible, manufacturer‑specified performance.
