GC columns achieve the highest levels of PEG stationary phase inertness performance for a range of challenging active analytes with individually-tested DB-WAX UI columns.

• Improved peakshape for challenging polar compounds with DB-WAX Ultra Inert
• Reliable column to column inertness performance
• Equivalent bonded polyethylene glycol (PEG) selectivity as 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

DB-WAX Ultra Inert (UI) represents the ultimate performance of PEG stationary phase inertness because it provides 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. This ensures 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. Having the same selectivity as J&W DB-WAX makes upgrading to Ultra Inert performance easy with minimal validation when switching to DB-WAX UI. No need to recreate or modify existing compound libraries that are based on DB-WAX selectivity.
