Method and device for dispersiometric analysis of threehyphen;component liquid mixtures

摘要

Analysis of liquid threehyphen;component mixtures by twohyphen;wavelength refractometric measurement is described. The method is applicable to systems with small additivity rule deviation. The results are presented in the form of differences between the refractive indices of the mixture and the individual components. A device for simultaneous measurement of all parameters is described. This fourhyphen;channel differential refractometer helps determine the refractive index differences with an accuracy better than 3times;10minus;6, eliminating the necessity of rigorous temperature control. thinsp;
