超高效液相色谱—串联质谱法测定植物油中甲胺磷残留量的不确定度评定
Evaluation of uncertainty in determination of methamidophos residue in vegetable oil by ultra-performance liquid chromatography-tandem mass spectrometry
摘要
Abstract
[Objective]To evaluation the uncertainty of determination of methamidophos residues in vegetable oil by ultra-performance liquid chromatography-tandem mass spectrometry.[Methods]A vegetable oil sample was detected by ultra-high performance liquid chromatography-tandem mass spectrometry,and the recovery rate was determined at the same time.By analyzing the sources of uncertainty in the experimental process,the measurement uncertainty was ultimately evaluated.[Results]The residue amount of methamidophos in olive oil samples was not detected,and the uncertainty of the accuracy 1 sample was evaluated,The results were(0.018±0.010)mg/kg.[Conclusion]In the uncertainty measurement process of methamidophos residue in vegetable oil,the influence of standard curve fitting,ultra-high liquid chromatography-mass spectrometry,and standard working solution is relatively large,while the influence of sample weighing,sample pretreatment,and sample repeatability determination is relatively small.关键词
