An accurate determination method of fatty acid methyl esters (FAMEs) in biodiesel produced from pistacia chinensis oil by gas chromatography (GC) was developed, with methyl tridecanoate used as an internal standard. The results show that the standard calibration curves for the FAMEs have good linearity over the concentration range, the linearity correlation coefficients (R2) are more than 0.99 for all the components. The average recoveries are from 95.26% to 99.66%. The method has good precision with the RSD ranging from 1.03% t...
