Abstract
A method for recording the boiling curve of liquids, in particular petroleum products and/or solvents, in which a sample amount of the liquid to be analyzed is evaporated and subsequently condensed, wherein the vapor temperature and the respectively evaporated amount of liquid are monitored. The sample amount is dosed by a filling means, particularly a pump, wherein the filling means and the condensate collection chamber are brought to a defined, and preferably identical, temperature level. The condensed volume is determined volumetrically in a manner known per se and the distillation residue of the sample amount is determined by weighing.
Claims16
A device for recording the boiling curve of liquids, wherein the filling means (1), particularly a pump, for filling in a sample amount is connected with a duct leading to a sample dish (7), that the sample dish (7) is connected with a distillation apparatus, particularly a condenser (15), that the filling means and the distillation apparatus, particularly the condenser (15), are made of well heat-conducting material, particularly metal, and that the filling means (1) and the condenser (15) are connected to a temperature controller.
A device for recording the boiling curve of liquids, which comprises:
- a sample dish;
- filling means connected to the sample dish to fill the sample dish;
- a distillation apparatus connected to the sample dish;
- and
- a temperature controller connected to the filling means and the distillation apparatus,
- wherein the filling means and the distillation apparatus comprise material that conducts heat well.
