| Abstract: | The uncertainty during process of lead and total arsenic determination in soy sauce by inductively coupled plasma-mass spectrometry(ICP-MS)were estimated based on the mathematical model.The uncertainty sources were identified as four parts,standard solution preparation,sample preparation,sample determination using calibration curve and reagent blank.Each source was quantified in detail.Finally,combined standard uncertainty as well as expanded uncertainty was calculated. |
