摘要:
痕量元素及其同位素采集、预处理和分析在海洋研究中具有重要的作用,由于含量极低,在采样、样品预处理及分析过程中容易受到外界污染源沾污。通过在一个20尺标准超高集装箱内制作一套移动式海水痕量元素洁净采集实验室,完成对实验室空间设计、空气质量控制,样品快速转移,实现水样上船后快速进入到洁净环境中,减少样品暴露在大气中时间,在洁净环境中高效完成样品取样、过滤和预处理等操作。所有操作满足GEOTRACES组织有关痕量元素采集的规范要求,从源头上保证分析测试结果的可靠性。

Abstract:
The collection, pretreatment, and analysis of trace elements and their isotopes play an important role in marine research. However, samples are easily contaminated by external pollution sources in the process of sampling, sample pretreatment, and analysis because of their minute quantities. A mobile clean collection laboratory for the study of trace elements in seawater was developed in a 20-foot standard super high container. The laboratory space design, air quality control, and sample rapid transfer have been completed. After boarding the ship, water samples can enter the clean environment quickly, reducing exposure time of the samples in the atmosphere and efficiently completing the sampling, filtering and pretreatment of the sample in a clean environment. All operations meet the requirements of GEOTRACES for trace element acquisition, ensuring the reliability of analysis and test results from the source.
Key words:  trace elements in seawater  clean collection  mobile laboratory
