【Abstract】 We have taken part in inter laboratory comparisons of total N and \+ 15 N 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 \+ 15 N abundance are absolutely perfect and accurate. This EQA plan should be useful in defining our laboratory testing proficiency and testing level in inter laboratory.更多还原
