Abstract
Fatty acids in a diverse array of sample types can be derivatized and profiled using reactive pyrolysis – gas chromatography (RxPY), which is, in essence, thermally assisted hydrolysis and methylation. Both solid and liquid samples are analyzed directly. When m‐trifluorophenyltrimethyl ammonium hydroxide is used as the organic alkali, analytical precision is on the order of 1%RSD. Quantitative data using ether standard addition or external standard yield accuracies within 5%. The analysis of omega‐3 acids in krill oil is used to illustrate the benefits of using RxPY‐GC.
