Agilent DB-WAX Ultra Inert 30m, 0.53mm, 1.0um 125-7032UI

The Agilent DB-WAX Ultra Inert 30 m, 0.53 mm, 1.0 µm (catalog 125-7032UI) is a fused‑silica capillary gas chromatography column with a bonded polyethylene glycol (DB‑WAX) Ultra Inert stationary phase. It is designed to provide enhanced inertness and symmetric peak shape for challenging polar and active analytes, enabling reliable GC analysis of acidic and polar compounds. Typical use cases called out by the manufacturer include analysis of free fatty acids, alcohols, diols, aldehydes and other polar species where reduced adsorption and consistent column‑to‑column performance are required.

Key Features:

• Length: 30 m
• Inner Diameter (ID): 0.53 mm
• Film Thickness: 1.0 µm
• Phase/Type: DB‑WAX Ultra Inert (high‑polarity PEG stationary phase)
• Capillary Tubing: Fused silica
• Format: 7 inch; Temperature range: 20 °C–230/240 °C

Advantages:

• Ultra Inert QC testing delivers consistent column‑to‑column inertness for active analytes, reducing variability between columns.
• Improved peak shape and response for challenging polar compounds, minimizing adsorption and tailing.
• Selectivity equivalent to standard DB‑WAX allows upgrading without method revalidation or changing compound libraries.
• Bonded, crosslinked PEG phase is solvent‑rinsable and tolerates aqueous injections, improving robustness for acidic sample types.
