Uncertainty Evaluation of Malathion Pesticide Residues in Cucumber by GC |
| |
Abstract: | Through the analysis of the determination process of Malathion pesticide residues in cucumber by gas chromatography(GC),Uncertainty sources of measure results were analyzed by establishing a measurement model,Components of uncertainty were evaluated,combined uncertainty and expanded uncertainty were calculated.Results show that main uncertainty sources of measure results is preparation of standard solution and repeated determination. |
