Refractive index factors
WebThe two factors on which the refractive index of a medium depends are: Nature of a medium i.e., its optical density (e.g. μg = 1.5, μw = 1.33). Smaller the speed of light in a medium relative to air, higher is the refractive index of that medium. WebChange in Refractive Index When degassing unit Is Switched from OFF to ON With no column, 1.0 mL/min flowrate, and DGU- 20A3 degassing unit. This graph shows two things. 1) Decreasing the dissolved air in the eluent increases the refractive index. 2) The change in refractive index is greater for THF than for water.
