Abstract

Traceability and reliable results are the two pillars of analytical methods; certified reference materials (CRMs) meet this requirement. ISO 17034:2016 credentials provide brief information on general requirements for the competence of Reference Material Producers (RMPs). The different types of CRMs have been produced in recent years for chemical analysis in food, water, soil, and sediment matrices in recent years. This review provides a detailed overview of the development of CRMs in the field of marine environment, as matrix CRMs play an important role in the field of environmental monitoring. COMAR database, EVISA database: materials, LGC standards, and JRC catalogs are very helpful online resources to find various types of CRMs according to the application requirements.

• Highlights

• The classification of certified reference materials (CRMs) in the field of marine environment is presented;

• General information about the production and characteristics of CRMs is discussed;

• Examples of use of existing marine CRMs are described in detail;

• Importance of CRMs for QA/QC and CRMs development for chemical analysis is presented;

• The parameters that characterize the CRMs: representativeness, homogeneity, stability, and certified value are provided.

摘要

可追溯性和可靠的结果是分析方法的两大支柱；有证标准物质 (CRM) 符合此要求。ISO 17034:2016 证书提供了有关参考材料生产商 (RMP) 能力的一般要求的简要信息。近年来，已经生产了不同类型的 CRM，用于食品、水、土壤和沉积物基质中的化学分析。本综述详细概述了 CRM 在海洋环境领域的发展，因为矩阵 CRM 在环境监测领域发挥着重要作用。COMAR 数据库、EVISA 数据库：材料、LGC 标准和 JRC 目录是非常有用的在线资源，可以根据应用要求查找各种类型的 CRM。

• 强调

• 介绍了海洋环境领域有证标准物质（CRMs）的分类；

• 讨论了有关 CRM 的生产和特性的一般信息；

• 详细描述了现有船用 CRM 的使用示例；

• 介绍了 CRM 对 QA/QC 和 CRM 开发对化学分析的重要性；

• 提供了表征 CRM 的参数：代表性、同质性、稳定性和认证值。
