Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the Second Institute of Oceanography, State Oceanic Administration. This standard is under the jurisdiction of the National Marine Standardization Technical Committee (SAC/TC283). This standard was drafted. Second Institute of Oceanography, State Oceanic Administration, Zhejiang University. The main drafters of this standard. Lu Haiyan, Wang Zhengfang, Zhang Shiyong, Zhou Qingsong. Development and storage of reference materials for analysis of seawater components specifications

1 Scope

This standard specifies the methods and technical requirements for the development and storage of reference materials for the analysis of seawater components. This standard is applicable to the development and storage of reference materials for the analysis of inorganic components in seawater. For other reference materials for the analysis of components, please refer to this standard.

3 Terms and definitions

The following terms and definitions established by JJF1005-2005 and are applicable to this document. 3.1 Standardized seawater seawaterspikedwithreferencematerial(s) A standard substance prepared by using ocean sea water as a substrate and adding one (or more) elements or chemicals with a known amount to it. 3.2 Matrix certified reference material They are usually real samples containing characteristic quantities. They exist in the natural environment in their natural form, and they can also be added to the matrix.

4 Preparation of standard materials for analysis of seawater components

4.1 Candidates for seawater reference materials To prepare standard materials for the analysis of seawater components, ocean seawater should be selected as the seawater matrix sample, and then added to the standard; offshore seawater can also be selected as Candidates for direct valuation. If the standard substance used for a specific purpose can be selected as the sea water matrix sample of the project, it can be directly Set value. The unspiked seawater is directly prepared as a standard material, and it can become a certified standard material of the matrix. 4.2 Preparation of seawater reference materials 4.2.1 Water harvesting tools Magnetic plastic pumps for ocean water harvesting; engineering plastic water harvesters such as compound-back water harvesters can be used for offshore water harvesting. Refer to 4.2.2.2 before collecting water The plastic parts that touch the sea water are cleaned and rinsed with on-site sea water. ......
