| In the question of the detection limit , the basic concept is consistent. Namely: the detection limit is a given analysis, which can detect the minimum concentration or content of the measured elements in a reasonable and confident level . Differences occur in how to measure and calculate directly by the detection limit , there is no unified regulations at the present time. |

| 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. |
