DB-WAX GC Columns
Agilent J&W DB-WAX is ideal for food, fragrance, and flavor applications. The column's lower temperature limit of 20 °C improves resolution of analytes with low boiling points.
- Polyethylene glycol (PEG)
- Close equivalent to USP Phase G16
- High polarity
- Lower temperature limit of 20 °C is lowest of any bonded PEG phase; improves resolution of low boiling point analytes
- Column-to-column repeatability
- Bonded and cross-linked; solvent rinsable
- Exact replacement of HP-WAX

DB-WAX Ultra Inert GC Columns
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 Agilent 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.
- Improved peakshape for challenging polar compounds
- 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
- Bonded and crosslinked phase is solvent rinse able and tolerates aqueous injections

DB-FATWAX Ultra Inert GC Columns
DB-FATWAX Ultra Inert (UI) is an application-specific PEG-type GC column designed for the separation of fatty acid methyl esters (FAMEs), fatty acid ethyl esters (FAEEs), and fatty acids. This column is tested with a FAME mixture to ensure reproducible FAME equivalent chain length (ECL) values, proper identification of important FAMEs such as EPA, DPA, and DHA, and resolution of key pairs of FAMEs.
- Application-specific columns for FAMEs, FAEEs, and fatty acids
- Individually tested with a FAME mixture and Ultra Inert Wax test probe
- Reliable column to column inertness performance
- Improved peak shape for challenging polar compounds such as free fatty acids

- Bonded and cross-linked phase is solvent rinseable and tolerates aqueous injections
DB-HeavyWAX GC Columns
The Agilent J&W DB-HeavyWAX Polyethylene Glycol (PEG) is a high temperature WAX column that can operate at higher maximum temperatures compared to standard WAX columns. The higher maximum temperature limit allows for shorter run times, providing a lower cost per test. The column provides retention time stability and increased column lifetime, even when used at maximum operating temperatures. The ability to bake out the column at the end of the analysis reduces sample matrix effects, limiting carryover and the risk of ghost peaks. The column also exhibits very low bleed, which results in better signal-to-noise ratios and lower detection limits (LOD), especially for late eluting compounds.
- Polyethylene Glycol selectivity
- Maximum operating temperatures of 280 °C isothermal and 290 °C programmed
- Fast analysis: shorter run times due to extended temperature limit
- Retention time stability and increased column lifetime even when used at maximum operating temperatures
- Ability to bake out the column at the end of the analysis to reduce sample matrix effect, and limit carryover and the risk of ghost peaks
- Extended list of analytes to higher molecular weight compounds
- Broader application range for multidimensional GC applications as the oven temperature can be increased compared to standard WAX column
