DB-23

DB-23 GC Columns from Agilent

Agilent J&W DB-23 is specifically designed for the high-quality separation of fatty acid methyl esters (FAMEs). It is bonded, cross-linked and solvent-rinsable, and is a close equivalent to USP phase G5. DB-23 has excellent resolution, highly suited for procedures using cis and trans FAME isomers, and a wide operating temperature range.
