有证标准物质(CRMs)是具有准确量值的测量标准,在分析方法研究和评价、定性和定量分析、矿产勘查、仲裁检验、质量监督检验等领域发挥着重要的作用。20世纪80年代成立的国际标准物质数据库(COMAR)是目前国际上最大的CRMs 数据库,收录来自25个成员国274个生产机构提供的CRMs 数量超过10200种。本文从CRMs 的数量、分类、发展变化等角度全面评述了国际数据库COMAR,阐述了欧盟组织、美国、中国、日本、澳大利亚等成员国的标准物质研究情况。英、美、法、德等国家的标准物质研究开展较早,研究水平高,处于世界领先地位;中国、日本等亚洲国家标准物质的发展虽起步晚,但发展迅速,已成为向COMAR 提供CRMs最多的两个国家,分别为1194种和1456种(截至2013年8月)。COMAR 建立以来,工业、有色金属和物理特性三大传统应用领域的CRMs 占COMA 数据库总CRMs 的份额一直较大,比例始终保持50%以上,其中工业领域的CRMs 数量最多,占19%;有机、生物与临床类CRMs 所占份额最少,仅为7%和3%。随着社会需求的增加, 生物与临床、生活质量领域标准物质成为未来标准物质发展的热点方向。本文指出,未来标准物质的发展将由过去的钢铁、有色金属、物理特性等传统领域逐渐转向食品安全、环境保护、气候变化、临床医学、制药产业、生物能源等新兴领域,标准物质的研究制备、定值及不确定度将面临新的技术挑战。 |

Certified reference materials(CRMs)are standard materials with certified quantity values,playing important roles in development and assessment of analytical methods,qualitative and quantitative analysis,mineral exploration,arbitration inspection,quality supervision and inspection. The Code d' Indexation des Materiaux de Reference(COMAR),founded in the 1980s,is now the largest international database for CRMs. It contains over 10200 CRMs provided by 274 institutions from 25 member countries so as to integrate superior resources. The CRMs' quantity,classification and development variation,as well as the current research situation of CRMs in member countries such as the European Union,America,China,Japan and Australia are presented in detail. Countries like the United Kingdom,the United States,France,and Germany developed the CRMs research early, and kept ranking international top with high research level. Asian countries like China and Japan started CRMs research late,but developed fast,and now become the top two CRMs providers in COMAR with the respective amount of CRMs up to 1194 and 1456 by August 2013. Since the establishment of COMAR,CRMs in three traditional application fields including industries,non-ferrous,and physical properties have been a large proportion of the total quantity of CRMs in COMAR,which is up to 50%. Among them,the field of industries had the largest quantity of CRMs,accounting for 19%. While the fields of organics-biology and clinic had the least share of CRMs,accounting for only 7% and 3%,respectively. Along with increasing social demand,the fields of biology and medicine,together with quality of life have become the hotspots of current CRMs' development. This article also highlights that,instead of the traditional fields of ferrous,non-ferrous and physical properties,the development focus of CRMs research will turn to the fields of food safety,environmental protection,climate change,clinical medicine,pharmaceutical industry,and bio-energy in the future. Accordingly,the preparation,characterization, and uncertainty assessment of CRMs will face new technical challenges. |
