摘要

从SI可追溯的密度测量和折射测量结果中确定盐度值使SI可追溯性成为可能。在这项工作中，通过这两种方法在超纯水溶液和两种不同标准海水(OSIL和ERM)溶液中测定氯化钠的盐度的计量兼容性的简短研究，在[35.0;215.0] g kg−1区间，给出。证明了所述区间内盐度测定的计量相容性。当出现最大盐度值时，可以测试基质对测定的影响，并得出密度测定技术的优选使用结论。

Absolute salinity determination by oscillation-type densimetry and refractometry

The determination of salinity values from SI traceable densimetry and refractometry measurement results enable SI traceability of the former. In this work, a short study of the metrological compatibility of salinity determinations via these two methods for sodium chloride in ultrapure water solutions and two different standard seawaters (OSIL and ERM) solutions, in the [35.0; 215.0] g kg−1 interval, is presented. It evidenced the metrological compatibility of the salinity determinations in the referred interval. The largest salinity values enabled to test the matrix effect upon the determinations and concluded the preferable use of densimetry technique, when occurring.
