Agilent DB-WAX Ultra Inert 30m, 0.25mm, 0.50um 122-7033UI

The Agilent DB-WAX Ultra Inert 122-7033UI is a gas chromatography (GC) fused‑silica capillary column featuring Agilent's DB‑WAX Ultra Inert polyethylene glycol (PEG) stationary phase. It is designed to deliver enhanced inertness and symmetric peak shapes for challenging polar analytes (for example free fatty acids, alcohols, diols and aldehydes) and is recommended for applications such as food, flavor and fragrance analysis, industrial chemical analysis, QC and method development. The column preserves DB‑WAX selectivity while improving response for active compounds and is available in 7‑inch format for standard GC installations.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.50 µm
• Phase: DB‑WAX Ultra Inert (PEG, high polarity)
• Capillary tubing: fused silica; Format: 7‑inch
• Temperature range: 20 °C to ~240/250 °C

Advantages:

• Ultra Inert PEG phase gives improved peak shape and higher response for polar/active compounds, reducing adsorption and degradation
• Individually tested for reliable column‑to‑column inertness, minimizing variation between columns
• Same DB‑WAX selectivity so existing methods and libraries generally do not require revalidation
• Bonded and crosslinked phase is solvent‑rinseable and tolerates aqueous injections useful for food and QC workflows
