Abstract
Disclosed are methods and apparatus for determining phase transition temperatures and, more particularly, for determining cloud, fluidity, freezing, and haze points of hydrocarbon fuels and hydrocarbon/oxygenate fuel blends. The attenuation of laser light as it passes through the sample, then through a laser line filter, and then into a photodetector is used to determine the transition temperature.
