Agilent DB-1 30m, 0.32mm, 0.10u 123-1031

The Agilent DB-1 GC column (part 123-1031) is a 30 m, 0.32 mm ID fused-silica capillary column with a DB-1 (dimethylpolysiloxane) stationary phase and a 0.10 µm film thickness. It is a non-polar, low-bleed column designed for general-purpose gas chromatographic separations and compatible with high-temperature methods. The DB-1 phase is bonded, cross-linked and solvent-rinsable and is equivalent to USP phase G2. Typical applications include separation of hydrocarbons, volatile and semi-volatile compounds where fast elution and thermal stability are required.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.32 mm
• Film thickness: 0.10 µm
• Phase: DB-1 (dimethylpolysiloxane)
• Capillary tubing: fused silica
• Temperature range: -60 °C to 325/350 °C
• Format: 7-inch cage
• USP designation: G1, G2, G38, G9

Advantages:

• Non-polar, low-bleed construction with high temperature stability for reliable high‑temperature elutions and extended column life.
• Thin 0.10 µm film supports faster elution and improved analysis of volatile compounds and fast GC methods.
• Bonded, cross-linked and solvent-rinsable phase offers robustness and the ability to clean/regenerate the stationary phase.
• Equivalence to USP phase G2 facilitates method transfer and compatibility with USP-referenced procedures.
