APPARATUS FOR THE MEASUREMENT OF CHEMICAL ACTIVITY COEFFICIENTS OF GAS PHASE SPECIES IN THERMODYNAMIC EQUILIBRIUM WITH LIQUID PHASE

摘要

The invention relates to an apparatus comprising a fluidic part (10) intended to contain a sample; an analytical part (30) comprising a waveguide (32); and a permeable membrane (20) closing the fluidic part (10), so as to physically separate the fluidic part (10) from the analytical chamber (30).
