Evaluation of Uncertainty for Determination of Cadmium in Oratosquilla oratoria by ICP-MS Linking Microwave Digestion Method
This study used the microwave digestion inductively coupled plasma mass spectrometry(ICP-MS)method to determine the uncertainty of cadmium content in crayfish,calculated each uncertainty component,and evaluated its expanded uncertainty.The results indicate that stable instrument status,qualified measuring instruments,qualified standard products,suitable standard curves,parallel measurements,and skilled technical personnel are the key points to improve the accuracy of results.
