We have been able to give uncertainty estimated value for a given method, therefore, in turn, once a confidence reasonable level is given , we can use this calculation model of the uncertainty estimated value to find the detection limit. For example, when we limit the quantification detection to 30% tolerance (95% confidence level), we can use the uncertainty continuous transfer model to calculate the x and dx values with different values of y, and take extended factor of 2, then find the point of the relative difference of 30% . The reason why there are differences in the past, it lies in there's no ways to make the uncertainty deliver effectively when the calibration curve is made to fit ºÜÈÙÐÒΪ´ó·½µÄÎÊÖ÷·þÎñ ÄÜÁ¦ÓÐÏÞ ¼ûÁ |

| The special significance of the detection limit can accurately assess a given method in the detection ability of low concentrations level .Half a century, people are more unified the definitionon of detection limit on the concept ,but on the question of how to correct or more accurately to assess detection limit,the international analysis Jie remains controversial.After retrieval, the major international organizations , according to the actual situation in their respective areas of expertise, accordingly made the definition and provisions of the detection limit, determination limit (limit of quantification), detection limit and so , but not exactly identical. |
