The production of experimental data for CO2 solubilities in the H2O-CO2-NaCl is of first importance to constraint thermodynamic modelling of CO2 geological storage. Here a mcirocapillaries device is coupled to a Raman microspectrometer to measure CO2 solubility as a function of pressure, temperature and NaCl concentration. The results show an excellent correlation with the equation of state of Duan and Sun [1] and with previous works [2].
