DB-WAX Ultra Inert

Agilent DB-WAX Ultra Inert Columns

Agilent DB-WAX Ultra Inert (UI) GC columns deliver enhanced performance for the analysis of polar compounds, offering exceptional inertness, sharper peak shape, and greater sensitivity than traditional polyethylene glycol (PEG) WAX columns. Built on the proven selectivity of the original Agilent J&W DB-WAX phase, these UI columns allow seamless method transfer without recalibration or changes to existing compound libraries.

Engineered with Agilent’s advanced Ultra Inert deactivation technology, DB-WAX UI columns significantly reduce analyte adsorption—especially for active or oxygenated compounds—ensuring reproducible quantitation across food, environmental, fragrance, alcohol, and flavor applications. Analysts benefit from lower bleed, improved baseline stability, and reliable performance even at elevated temperatures.

Chrom Tech proudly supplies the full portfolio of Agilent DB-WAX UI columns, backed by fast shipping, competitive pricing, and expert technical support to help you optimize your GC and GC/MS workflows.

Upgrade to DB-WAX Ultra Inert for more confident identification, smoother method transfer, and robust long-term column stability—without compromising the selectivity you rely on.

Key Definitions â–¸
Ultra Inert (UI) Deactivation
Agilent’s advanced deactivation technology that minimizes surface activity inside the column, improving recovery and peak shape for polar, reactive, and high-boiling analytes.
WAX / PEG Stationary Phase
A polyethylene glycol phase designed for highly polar compounds such as alcohols, aldehydes, fatty acids, flavors, and fragrance components—widely used in food, environmental, and industrial applications.
Low Bleed
The reduced release of stationary-phase components at elevated temperatures, resulting in a cleaner baseline, improved sensitivity, and more accurate mass-spectral identification.
Equivalent Selectivity
DB-WAX UI columns match DB-WAX selectivity exactly, enabling seamless method transfer, unchanged retention times, and full compatibility with existing compound libraries.
Frequently Asked Questions â–¸
What makes DB-WAX UI different from standard DB-WAX columns?
DB-WAX UI columns use Agilent’s Ultra Inert deactivation to provide improved recovery, reduced adsorption, and cleaner baselines—especially important for reactive or polar analytes.
Can I transfer my existing DB-WAX methods to DB-WAX UI?
Yes. DB-WAX UI columns maintain identical selectivity and retention to DB-WAX, enabling direct method transfer without modifying compound libraries or retention indices.
Which applications benefit most from DB-WAX UI columns?
These columns excel in analyses of alcohols, aldehydes, solvents, flavors, fragrances, and other polar organics where peak symmetry, sensitivity, and low bleed are critical.
