| Abstract: | Based on GB/T 5009.17 - 2003, the content of hydrargyrum can be determined with atomic fluorescence spectrometry. By the experiment of uncertainty measurement of the hydrargyrum in fungus, a method to evaluate the uncertainty measure for standard curve method was developed. The combined standard uncertainty and the expanded uncertainty are expressed, which provide the effective and credible quality data for the quality control. |
