| Abstract: | Evaluation of standard uncertainty of the calibration curve was calculated on the basis of the principle of method of least squares,and the sources of uncertainty of the analytical process were analyzed and distin-guished fully and amply.The uncertainty in measurement of the determination of arsenic Speciation was evaluated comprehensively.Theoretical information were provided for determ ination of arsenic in vegetables. |
| Keywords: | Arsenic speciation HPLC-HGAFS Vegetables Uncertainty |
