dc.description.abstractThe purpose of the present communication is to study the metrological compatibility of measurement results of mass fractions of sodium chloride in aqueous solutions, by different analytical techniques: refractometry and oscillation-type densimetry. In complement pH measurements were made in solutions of NaCl of 3,5 cg g -1 and in a synthetic seawater standard (OSIL). Previously, metrological compatibility of measurement results with refractometer and oscillation-type density meter was showed for aqueous solutions of glucose, from 2 cg g -1 to 42 cg g -1 . Due to its interest for the food science and health science, sodium chloride mass fraction in aqueous solution between 0,5 cg g -1 and 7 cg g -1 and for brine systems were also measured. Comparison was displayed between potentiometric pH and pH deduced by salinity experimental value.en
