蒸馏法检测轻苯终点主要误差来源及管控

Main source of error and its control for light benzene end point measurement by distillation method

蒸馏法检测轻苯终点是国家标准规定的方法,但检测过程容易产生误差,造成检测结果失真。通过对检测环节与要素的分析和研究,确定了主要误差来源,提出了减小误差的方法和措施,从而提高准确性。

Light benzene end point measurement by distillation method is an official measurement as per Chinese national standard, during which errors would occur and the test result would be inaccurate. This paper analyzes the testing details and finds out the source of errors and puts forward a solution to minimize the errors.
