Abstract
Infinite dilution activity coefficients (.gamma..infin.) are determined for a binary liquid system utilizing dual molecular beams. The vapors from two liquid systems, at least one of which is a binary liquid system, are collimated into molecular beams. The molecular beams are alternately chopped before being detected by mass spectrometer. The output from the mass spectrometer is representative of the difference in partial pressure for any component in the two liquid systems. The output from the mass spectrometer can be utilized to calculate .gamma..infin. for the binary liquid system.
