Linearity and range samples were serially diluted from each
oleic acid and fatty acid stock solution to obtain five concentration
levels, covering QL to at least 125% of the assay level. The peak
areas at each level of oleic acid and each individual fatty acid were
calculated to assess the method linearity. Graphs of each peak area
versus each corresponding concentration of fatty acid were plotted.
The correlation coefficient of the regression line for each fatty
acid standard ranged from 0.9998 (C14:0) to 0.9995 (C20:0). The
detailed results are summarized in
