Abstract
A Method and apparatus to accurately measure and display various properties of hydrocarbons and petroleum factions for a small volume of sample in a short period of time in one test with less cost and energy for the analysis by the method of light refection. The refraction of light through the sample is measured and compared to the refraction f the light through vacuum by the apparatus. The method of the invention comprises a property estimation from the apparatus to output a property estimate value. The property estimation means is equipped with a property estimation model for evaluating the property estimate value outputted from the property estimation model. The method is incorporated into standard or otherwise any refractive index test apparatus or refractometer to provide accurate measure of the thermodynamic and transport properties of pure hydrocarbons and undefined multicomponent mixtures such as petroleum factions.
