Abstract

PURPOSE: To accurately measure fuel oil C, crude oil, etc., by maintaining a liquefying tank, measurement chamber, and the transferring route of a liquid to be measured at constant temperatures, respectively. CONSTITUTION: An object to be measured, such as the fuel oil C, crude oil, etc., liquefied in a liquefying tank 22 is carried to a measurement chamber 24 by means of a pump 23. In the measurement chamber 24, the object to be measured is analyzed for components by irradiating the object with near infrared to infrared rays while the object is passed through a cell and measuring the variation of the absorbency of the rays. After measurement, the object is sent to a boiler, etc. Here, a flow rate controller 21 raises the temperature in a thermostatic chamber 20 to a prescribed value by controlling the flow rate of not water or steam. The chamber 20 maintains the liquefying tank 22, measurement chamber 24, and the transferring route of the object from the tank 22 to the chamber 24 at constant temperatures so as to prevent the solidification of the fuel oil C, crude oil, etc. Therefore, the fuel oil C, crude oil, etc., can be measured with accuracy, because the high-boiling-point substances do not solidify during measurement.

3. A near-infrared spectroscopic analyzer for irradiating an object to be measured introduced into a measuring chamber with measurement light in the near-infrared region and measuring a change in absorbance of the irradiated light to analyze the components of the object to be measured. In the storage case forming the measurement chamber, a first ball lens provided in the storage case and irradiated with light in the near infrared region, and provided in the storage case, A second ball lens for receiving the light of the first ball lens; and a second ball lens which is detachably attached to the storage case and is provided between the first ball lens and the second ball lens. A cell through which the object to be measured passes, and a connecting means for connecting the joint and the cell for introducing the object to be measured into the measurement chamber, and measuring the object to be measured by guiding the cell. And near infrared spectroscopy analyzer.
