The problem of the dependency of the instrumental constant K of vapor pressure osmometry on the molecular weight of the sample was studied by measuringthe variation of temperature difference signals with time for four low molecular weight orgahic compounds and ten narrow MWD oligomeric polystyrene samples with known average molecular weights. A modified procedure for measuring VPO signals and data treatment which leads to more accurate number average molecular weight was proposed.
