摘要： Method for automatically distilling liquid specimens in a standardized distillation apparatus containing a heater, a distillation flask, a collecting cylinder and control and regulation means, characterized in that: the specimen is introduced into the distillation flask; this flask is positioned in the distillation apparatus; the specimen to be analysed is classified in a group defined by the standard selected; the distillation is started, with the amount of condensate collected in the collecting cylinder, the temperature of the evaporated vapor, the temperature of the liquid specimen present in the flask, together with an operating parameter of the heater, being constantly measured; and the measured values are sent to the control and regulating means that in return control the operating parameter of the heater so as to obtain, directly and automatically, distillation parameters in accordance with a standard.

摘要： The invention concerns a method for determining the vanishing temperature of petroleum product crystals, characterized in that it comprises the following steps: introducing the sample to be analyzed in a measuring cell (4), arranged in a cryostatic chamber (1); connecting a laser emitter (6) and an associated optical receiver (7) to pass an optical beam through the sample to be analyzed and recording the light intensity received by the receiver (7); gradually lowering the temperature of the cryostatic chamber (1) then increasing it again gradually while recording the curve representing the variations in the light intensity received by the receiver (7) based on the temperature; and determining the vanishing temperature of the crystals from said curve.
