Deliver the highest levels of PEG stationary phase inertness performance for a range of challenging active analytes.

• Improved peakshape for challenging polar compounds with DB-WAX Ultra Inert
• Reliable column-to-column inertness performance
• Bonded polyethylene glycol (PEG) selectivity equivalent to DB-WAX
• No method revalidation needed
• High polarity
• Equivalent to USP G16
• Excellent performance for acidic compounds, including free fatty acids – no need for FFAP type column
• Bonded and crosslinked phase is solvent rinseable and tolerates aqueous injections

DB-WAX Ultra Inert (UI) represents the ultimate performance of PEG stationary phase inertness, providing symmetric peak shape and improved response for challenging polar compounds. All DB-WAX UI columns are individually tested with an Ultra Inert Wax test probe mixture according to the strictest industry QC standards to ensure consistent column-to-column inertness performance for challenging active analytes such as free fatty acids, alcohols, diols, and aldehydes, with minimal compound adsorption or degradation. Since it offers the same selectivity as Agilent J&W DB-WAX, upgrading to Ultra Inert performance is easy, with minimal validation required – there's no need to recreate or modify existing compound libraries that are based on DB-WAX selectivity.
