Mineral Oils Refractive Index

PhosLube – Mineral Oils Refractive Index

The refractive index is the measurement of velocity of light in air to velocity within sample being tested. Density and viscosity readings go hand in hand with refractive index. Mineral oils refractive index is used for defining paraffin to napthene ratios. Manufacturers use refractive index as a process control tool. Refractive index measures aromatics, unsaturates, and is needed for determining different carbon compositions. The refractive index varies with wavelengths, depending on the degree of oil being analyzed. The refractive index is used within the electromagnetic spectrum. The velocity and the wavelength of the radiation are reduced, and the speed of light is used as a medium. The refractive index can be used in quantitative analysis and particle size analysis.
