英文关键词:% total N  ¹⁵N abundance  proficiency testing

中文摘要:

      参加了由FAO/IAEA组织的全氮和¹⁵N丰度检测能力验证的实验室国际间的比对.两年的比对结果表明,我们实验室对3个植株样品全氮和¹⁵N丰度的测定值与指定值十分吻合,检测结果准确.此项计划的实施,证明了本实验室的检测能力和在国际实验室间的水平

英文摘要:

      We have taken part in inter laboratory comparisons of total N and ¹⁵N abundance determination proficiency testing organized by FAO/IAEA. It was proven that our laboratory analytic results of three plant samples are identical with reference results in two comparisons. Our results of total N and ¹⁵N abundance are absolutely perfect and accurate. This EQA plan should be useful in defining our laboratory testing proficiency and testing level in inter laboratory.
