Uncertainty Evaluation for Determination of Aflatoxin M1 in Milk by High Performance Liquid Chromatography
The uncertainty of the determination of aflatoxin M1 in milk by high performance liquid chromatography mainly comes from the weighing of the substance to be tested,the constant volume of the substance to be measured,the preparation of standard solution,high performance liquid chromatograph and the recovery rate of the method.Among them.Through a lot of experimental data,the analysis shows that the basic level of aflatoxin M1 in milk is 0.201 5 μg·L-1.The uncertainty of aflatoxin M1 in milk is:X=(0.201 5±0.007 6)μg·L-1,k=2.
