【摘要】 讨论了研制适用于微分析质控的新一代有证标准物质(CRM)的必要性,以及NAA在新一代CRM认证中的作用。归纳了NAA在当代无机痕量分析计量学发展中的三个作用:NAA作为比较基准法的国际承认,将对现代CRM质量的提高作出贡献;k0NAA的同时使用,将进一步增强相对法NAA的基准法地位;NAA在适用于微分析质控的新一代CRM认证中将发挥不可替代的作用。更多还原

【Abstract】 The necessity of the development of new generation of certified reference materials （CEMs） and the role that NAA will play in the certification of those CRMs are discussed. In conclusion, the major role of NAA in the metrology of contemporary inorganic trace analysis is summarized: the international recognition of NAA as a primary ratio method will imply a major conrtibution to the improvement of CEMs; the concurrent use of k₀-NAA will further strengthen the position of relative NAA as a primary ratio method; and NAA will play an irreplaceable role in the creation of new generation of CRMs, that will eventually lead the establishment of quality control system for microanalysis.更多还原
