Uncertainty Measurement of Aflatoxins B]Determination from Corn Gluten Meal by High Performance Liquid Chromatography-Tandem Mass Spectrometry
GUM method and Top-down method were used to assessment measurement uncertainty of the aflatox-in B1 in corn gluten meal by high performance liquid chromatography-tandem mass spectrometry.By comparison of assessment process and assessment results of the two methods,it was found that the top-down method can make full use of laboratory test data and quality control data under the premise of simplifying the assessment steps and ensu-ring the reliability of the evaluation assessment results,and can introduce the uncertainty caused by the change of testers and the replacement of testing instruments.Therefore,top-down method was an objective and efficient un-certainty assessment method,providing a reference for accurate traceability of aflatoxin B1 detection data in feed.
