Abstract
Arrangement for measuring physico-chemical properties of liquid, such as solutions, dispersions and emulsions. The arrangement comprises a light source for producing and emitting light in the liquid, a detector for detecting said light after being scattered by said liquid, processing means arranged for receiving an output signal from said detector. The processing means is further arranged to calculate a maximum value of the mean square displacement <&Dgr;r > from the autocorrelation function g as a function of time and the value of the property from said calculated maximum value of the mean square displacement <&Dgr;r >.
