| Abstract: | The influencing factors of the uncertainty of measurement result for the Lysine in marine feeds by amino acid analyzer are discussed and modeled by mathematical expressions.The sources of the uncertainty of measurement were analyzed and calculated.The expanded uncertainty was obtained.The expanded uncertainty of measurement result of marine feeds is 0.020%(K=2),when the content of the Lysine in marine feeds is 3.08%. |
