液相色谱-串联质谱法测定蜂蜜中氯霉素残留量的不确定度

Evaluation of the Uncertainty in the Determination of Chloramphenicol Residue in Honey by LC-MS/MS

本文参照SN/T 1864-2007《进出口动物源食品中氯霉素残留量的检测方法液相色谱-串联质谱法》中检测方法,采用液相色谱-串联质谱(LC-MS/MS)法测定蜂蜜中的氯霉素残留量,按照JJF 1135-2005《化学分析测量不确定度的评定》的指导,通过建立数学模型,分析不确定度的来源,对其进行量化,由此确定影响检测结果的主要因素,反映该方法的置信度。

The chloramphenicol residues in honey was determined by SN/T 1864-2007.According to the direction in JJF 1135-2005,we confirmed the main factors affecting the detection results to evaluate the confidence of the method by building the mathematical model,analyzing and quantifying the sources of uncertainty separately.
