| Abstract: | Microwave digestion and inductively coupled plasma mass spectrometry were used to determine the content of cadmium in oyster powder,and the uncertainty of the determination method was evaluated to find out the factors affecting the uncertainty.The evaluation results show that when the cadmium content of the sample is 0.428 mg·kg-1,the expanded uncertainty is 0.0068 mg·kg-1(k=2),and the measurement result is(0.428±0.0068)mg·kg-1.The basic method of determining the uncertainty of cadmium content in oyster powder was established.This method is suitable for the detection results obtained by linear regression and can be used to reasonably characterize the reliability of the measurement results. |
