A PEG-type GC column designed for analysis of FAMEs (e.g., fish oil) and fatty acids.

• 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
• High polarity
• Equivalent to USP G16
• Bonded and crosslinked phase is solvent rinseable and tolerates aqueous injections

Agilent J&W DB-FATWAX Ultra Inert (UI) is an application-specific polyethylene glycol (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.
