| Abstract: | Using standard material and the sample to dissolving,at the same time,as the standard curve using solid standard material,evaluation of uncertainty for determination of silicon dioxide content in manganese ore was carried out by ICP-AES. The quantitative mathematical model of the method,the relative mathematical model and analysis sources of uncertainty in performance testing process were established to calculate the combined uncertainty,expand uncertainty and evaluate results. |
