【 摘 要 】
A method for estercontent determination in soybean methyl biodiesel was studied, using ethyl oleateas internal standard. A biodiesel sample was analyzed and had its purity estimatedas 92.8%. Method accuracy was evaluated by comparison with the result obtainedvia EN14103, with a relative difference of 0.1%. Repetitivity and intermediateprecision were estimated as 2 and 1.5%, respectively.
