In a two component liquid / vapour system of volatile liquids that shows strong deviations from Raoult's Law it is easy to measure the TOTAL pressure of the system as a function of compostion by using a manometer, etc. Is there any simple way to experimentally measure the PARTIAL pressure of each component in the mixture of vapours? I am asking this because Raoult's Law deals with partial pressures and so I assume that it must be possible to actually measure them, but I can't think how this might be done.
