摘要： PURPOSE:To make it possible to perform automatic measurement of a deposition point in a short time by measuring the amount of transmitted light at the deposition point of a specimen, and obtaining deposition temperature and dissipating temperature. CONSTITUTION:A specimen whose deposition point is known is injected into a specimen chamber 11 of a measuring cell 10 and stored. Light is inputted into the specimen from a light source 35. The amount of the transmitted light at the deposition point is detected with a photodetector 36 through an optical fiber 34. The detected amount of the transmitted light is used as a judging point and stored in the memory in a control part 40. Then, the specimen whose deposition point is known is discharged, and a specimen whose deposition point is unknown is injected and stored in the specimen chamber 11. Cooling and heating are performed, and the light is transmitted. the control part 40 stores the specimen temperature when the amount of the transmitted light becomes the same amount at the judging point during the continuation of cooling as deposition temperature. The specimen temperature when the amount of the transmitted light becomes the same amount at the judging point during the continuation of heating is stored as dissipation temperature. Then, cooling and heating are repeated. When the difference between the deposition temperature and the dissipating temperature becomes a value within the specified value, the dissipating temperature at this time is determined as the deposition point.

摘要： PURPOSE:To measure a distillation temperature in a short time by a method the discharge amount of a distillate part in relation to the total of the discharge amount of a part of not yet distilled and the discharge amount of the distillate part is detected as the distillation rate of a sample, and a sample temperature enabling the maintenance of a liquid level height of a vessel within a prescribed range is detected as the distillation temperature at said distillation rate. CONSTITUTION:When a distillation temperature for a specified distillate amount is measured, the flow ratio between a discharge pipe 38 for a part not yet distilled and a distillate discharge pipe 41 is adjusted in accordance with a distillate amount to be measured. In the state wherein valves 36 and 39 are closed, a sample is introduced from a sample introduction pipe 2 into a hermetically-closed vessel 12 so that it reaches the position of a liquid level height A, and heating is started. Then the liquid level lowers due to distillation. When it lowers to a position B, a valve 31 is opened and the sample is supplemented until the liquid level reaches the position of A. The liquid level in the hermetically-closed vessel 12 is always controlled to be between A and B in this way, and a sample temperature is measured successively. Besides, the liquid level of a fractional distillation vessel 8 is controlled to be between C and D constantly, and the valves 36 and 39 are started simultaneously to discharge the part not yet distilled, in order to fix a fractional distillation rate at this time.

摘要： PURPOSE:To reduce the amt. of a sample while miniaturizing a device and facilitating the washing of the device by providing a control part for automatically judging a pour point from the detection result of a sensor. CONSTITUTION:A control part 16 confirms the cooling of a sample at every definite unit temp. to instruct to close a valve 13, to operate the piston of a cylinder 12 and to supply air to a pressure pipe 10 and also issues a command for a sensor 8 to start the measurement of the surface of the sample in a storage part 3. At this time, when the sample has no flowability, the light from a light emitting part 8a is regularly reflected and, when the sample has flowability, the surface of the sample is swollen and the light from the light emitting part 8a is irregularly reflected and, therefore, the detection quantity of light in a light detection part 8b is different. The control part 16 input the detection quantity of light of the sensor 8 at every definite unit temp. to compare the same with the detection quantity of the sensor 8 preliminarily measured before pressurizing the sample. The control part 16 also measures the pressure in the pressure pipe 10 by a pressure gauge 15 and judges the temp. of the sample at a time when the pressure in the pressure pipe 10 reaches a definite value and the difference in the compared detection quantity of light is min. as a pour point.

The control part 16 confirms the cooling of the sample at certain steps, emits appropriate signal to a stepping motor 12a, moves a piston to the A-position, and regulates the air in a syringe 12 to a certain quantity. A certain amount of air is supplied to a pressure pipe 10, and a certain pressure is applied to the sample in the storage 3. The control part 16 sends appropriate signal to photosensors 8a, 8b to start the measuring of the sample, compares the photo- receiving amount of each photo-sensor with the corresponding value before pressurization, and judges whether any variation exists on the sample surface before and after pressurization.

摘要： PURPOSE:To considerably reduce variance in converted temperature even when the degree of pressure reduction varies by detecting a boiling point and the degree of pressure reduction and converting the temperature under atmospheric pressure according to the detection data and a predetermined correlation expression. CONSTITUTION:A sampling means A samples oil products as an object of boiling point measurement from on a production line by a specific amount in response to specific operation. A sample guiding-in means B guides the samples to a pressure-reduced boiling point meter C as the products are sampled. Then while the samples are placed under reduced pressure, a detecting means D detects the boiling point of the sample and the degree of pressure reduction of the pressure-reduced boiling point meter C in response to the distillation by the pressure-reduced boiling point meter C. A converting means E converts the detected boiling point detected corresponding to the detected degree of pressure reduction into the temperature under the atmospheric pressure according to the predetermined correlation expression. Then a discharging means F which is provided when necessary discharges the samples which are guided to the boiling point meter C from the boiling point meter C.

CONSTITUTION:The light transmitted through a filter 22 which allows the transmission of only the light of the wavelength region including the max. absorption of a sample out of the light from a light source 12 past a sample cell 18 is detected by a photodetector 24 and the light transmitted through a filter 26 which allows the transmission of only the light of the wavelength region where the absorbancy changes less with the characteristic of the sample is detected by a photodetector 28. The outputs from both detectors 24, 28 are compared by a comparator 32 and the difference therebetween is transmitted to an arithmetic circuit 36. The absorbancy of the absorption max. region in the absorption spectra of the compd. contg. the unsatd. multiple bonds in the petroleum product is measured and the correlation equation with the characteristic of the petroleum product is made. Said equation is preliminarily stored in the arithmetic circuit 36. The absorbancy of the unknown petroleum product is thereupon measured and is inserted into the correlation equation stored in the arithmetic circuit 36. The result thereof is outputted to a recorder 37.
