Agilent DB-5 30m, 0.32mm, 1.00u 123-5033

The Agilent DB-5 (catalog 123-5033) is a fused‑silica capillary gas chromatography column featuring a DB-5 stationary phase (5% phenyl‑methylpolysiloxane). It is 30 m long with a 0.32 mm inner diameter and a 1.00 µm film thickness, and is specified for low‑polarity GC separations. Typical applications include routine separation of volatile and semi‑volatile organic compounds in analytical GC workflows.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.32 mm
• Film thickness: 1.00 µm
• Phase: DB-5 (5% phenyl‑methylpolysiloxane)
• Format: 5‑inch capillary column
• Operating temperature range: −60 °C to 325/350 °C
• Polarity: Low polarity

Advantages:

• Low‑polarity DB-5 phase provides broad applicability for separating a wide range of volatile and semi‑volatile organic compounds.
• 1.00 µm film thickness increases sample loading capacity and improves retention for higher‑boiling analytes.
• 0.32 mm ID combined with 30 m length gives a practical balance between chromatographic efficiency and sample throughput.
• Wide operating temperature range (−60 °C to 325/350 °C) supports high‑temperature methods and robust routine analysis.
