水中氨氮和化学需氧量能力验证结果统计

Statistics of Proficiency Testing Results of Ammonia Nitrogen and COD in Water

能力验证是通过实验室间比对,按照预先制定的准则,评价参加者的能力。“水中氨氮、化学需氧量的测定”能力验证按照GB/T 27043-2012《合格评定能力验证的通用要求》、GB/T 28043-2019《利用实验室间比对进行能力验证的统计方法》及某省市场监督管理部门的相关要求实施。该能力验证项目的实施,可检验各检测机构对水中氨氮、化学需氧量的检测能力,帮助参加实验室发现并改正存在的问题,从而提高各检测机构的检测能力。

Competency verification is conducted through inter-laboratory comparisons to assess the competence of participants in accordance with pre-established criteria.The capacity verification of "Determination of Ammonia Nitrogen and Chemical Oxygen Demand in Water" shall be carried out according to GB/T 27043-2012 "Conformity Assessment—General Requirements for Proficiency Testing", GB/T 28043-2019 "Statistical Methods for Use in Proficiency Testing by Interlaboratory Comparison" and relevant requirements of the market supervision and administration department of certain province.The implementation of this capability verification project can test the detection ability of each testing institution on ammonia nitrogen and chemical oxygen demand in water, and help participating laboratories to find and correct existing problems, so as to improve the detection ability of each testing institution.
