摘要:
依据JJF1059—2012 《测量不确定度评定与表示》和CNAS-GL-06《化学分析中不确定度的评估指南》,建立了高效液相色谱法测定水产品中甲基睾酮残留的不确定度评定的数学模型。对测量过程中各不确定度来源进行分析,计算各不确定度分量,最后给出合成标准不确定度和扩展不确定度,评定结果表明:不确定度主要来源于测试过程的随机效应、曲线校准和样品处理过程。
关键词: 不确定度, 甲基睾酮, 高效液相色谱法, 水产品
Abstract:
According to the basic methods for uncertainty evaluation from Evaluation and Expression of Uncertainty in Measurement (JJF1059-2012) and Guidance on Evaluating the Uncertainty in Chemical Analysis (CNAS-GL-06) a mathematical model of uncertainty evaluation for the determination of methyltestosterone residue in aquatic products by HPLC was established. The sources of determination uncertainty were analyzed and each component of uncertainty was quantified. The combined standard uncertainty and expanded uncertainty were finally obtained. The major uncertainty sources were the random effects in testing process, curve calibration and sample pretreatment.
