Agilent DB-1 25m, 0.20mm, 0.33u 128-1022

The Agilent DB-1 25 m, 0.20 mm, 0.33 µm (catalog 128-1022) is a fused‑silica capillary gas chromatography column with a nonpolar DB‑1 phase. It is designed for general‑purpose GC separations where a low‑polarity, low‑bleed stationary phase and a high temperature capability are required. Typical uses include routine analyses of nonpolar to moderately polar volatile and semi‑volatile compounds and applications that demand stable performance at elevated oven temperatures.

Key Features:

• Length: 25 m
• Inner Diameter (ID): 0.20 mm
• Film Thickness: 0.33 µm
• Phase: DB-1 (low polarity)
• Capillary Tubing: fused silica; Temperature range: -60 °C to 325/350 °C

Advantages:

• Low‑polarity, low‑bleed DB‑1 phase supports sensitive detection and stable baseline at elevated temperatures.
• High maximum operating temperature allows analysis of higher‑boiling or thermally demanding compounds.
• Fused‑silica capillary construction with bonded/crosslinked phase offers solvent rinsibility and robust, repeatable performance.
• 25 m length with 0.20 mm ID and 0.33 µm film provides a balance of resolution and speed for general‑purpose GC separations.
