Activity Coefficients at Infinite Dilution

The dilutor method

Temperature range:             10°C-90°C
Pressure range:                   1 atm

The activity coefficient of the solute is determined from the decrease of solute concentration in the inert gas stream. The amount of solute in the inert gas stream has been determined by injecting a small amount of the stream with a sampling valve periodically to the gas chromatograph.
