Agilent DB-1 30m, 0.32mm, 0.25u 123-1032

The Agilent DB-1 123-1032 is a 30 m fused‑silica capillary GC column with a DB‑1 (100% dimethylpolysiloxane) stationary phase intended for general‑purpose gas chromatographic separations. It is described by the manufacturer as a nonpolar, low‑bleed, bonded and crosslinked column suitable for sensitive and high‑temperature analyses. The column is supplied in a standard 7‑inch cage format and is compatible with common Agilent GC systems.

Key Features:

• Length: 30 m.
• Inner diameter (ID): 0.32 mm.
• Film thickness: 0.25 µm.
• Phase: DB‑1 (100% dimethylpolysiloxane), low polarity.
• Operating temperature range: −60 °C to 325/350 °C.

Advantages:

• Low‑bleed DB‑1 phase improves baseline stability and sensitivity for trace‑level analyses.
• High temperature limit (up to ~325/350 °C) enables analysis of late‑eluting or high‑boiling compounds.
• Bonded, crosslinked and solvent‑rinsable construction offers robustness and the ability to clean the stationary phase for routine general‑purpose use.
