| Abstract: | A mathematic model using HPLC-RI for the uncertainty determination of sugar content in pepsin was established to analyze the factors which affect the uncertainty.Each component of factors was evaluated to calculate combined uncertainty.The combined standard uncertainty and the expanded uncertainty were finally obtained by synthesizing the uncertainties of various component variables.The findings show that the combined standard uncertainty is 1.92% and the expanded uncertainty is 4.1%.It is concluded that th... |
