Omegawax® Capillary GC Columns

This column allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components. Column Details: Phase: Bonded; poly(ethylene glycol) USP Code: G16 Length: 15, 30 m ID: 0.10, 0.25, 0.32, 0.53 mm df: 0.10, 0.25, 0.50

GC Analysis of Fatty Acids in Walnuts and Peanuts

Established methods from AOCSR and AOACR can be used to determine the fatty acid composition of nuts. This work demonstrates the application of aspects of these methods in the determination of the fatty acid composition of walnuts and peanuts. Data is presented showing analysis on GC capillary columns of three different selectivities: OmegawaxR, SP™-2560 and SLBR-IL111.
