Efficient Quality Control of Liquids with Density or Refractive Index Determination

Quality control of liquid samples without the measurement of density and refractive index is difficult to imagine today. Digital instruments have helped to make the determination of these two quantities become much more important. Density and refractive index are often determined at the same time. The measurement of both values makes the result more meaningful and can also be used to determine the concentration of multi-component mixtures. This article describes a number of examples of such applications.

  • Concentration determination in two-component mixtures
  • Quality control by means ofthe simultaneous determination of density and refractive index
  • Concentration determinations in multi-component mixtures
