依据GB/T 5009.140-2003《饮料中乙酰磺胺酸钾的测定》,用高效液相色谱法测定指定饮料中乙酰磺胺酸钾的含量。本文通过对整个测定过程中引起的不确定度进行分析,找出影响测量不确定度的因素,旨在了解用高效液相色谱法测定饮料样品中乙酰磺胺酸钾的含量结果的准确度,为评估测量结果提供科学依据。
According to GB / T 5009.140-2003 “Determination of Acesulfame-K in Beverages”, the content of Acesulfame-K in a given beverage was determined by high-performance liquid chromatography. In this paper, the uncertainty caused by the whole determination process is analyzed to identify the factors that affect the uncertainty of the measurement. The purpose of this article is to understand the accuracy of the results obtained by HPLC for determining the content of Acesulfame-K in beverage samples. Evaluation of measurement results provide a scientific basis.
