Evaluation of Detection Uncertainty of Lead in Sauce Detected with Flame AAS

Objective To evaluate the detection uncertainty of lead in sauce detected with flame AAS and to establish evaluation program and method. Methods Attribution approach or factor analysis, causal analysis and induction were adopted, Results We found out the main or important effect factors of detection result and established the causality classification chart for detection process. We concluded and advanced the main source of detection uncertainty and put forward the evaluation program and method of detection uncertainty. Conclusions The evaluation program and method fit the standard requirement and are simple and reliable. They have higher use value.
