Previously, following derivatization to their 2-nitrophenylhydrazide (2-NPH) derivatives, fatty acid (FA) abundances have been evaluated using high-performance liquid chromatography (HPLC). Although the method was sensitive, resolution was insufficient for many of the biologically important FAs. We have developed an enhanced
