Abstract

In this work, we have applied Optical Digital Interferometry approach to thermogravitational micro-column technique. By the new analysis, we examine the entire height of the micro-column and determine the complete concentration profile inside. The measurements were carried out by two lasers with different wavelength λ = 633nm and λ = 470nm. The system was validated with binary subsystems of the THN-IBB-C12 ternary mixture at equal mass fractions. The results were compared with values of Benchmark Fontainebleau and they showed an excellent agreement.
