発明の名称 (英語) SPECTROMETRY DEVICE UPDATE
発明の概要(英語) A spectrometry device according to the present invention is provided with: a spectral optical system that spectrally diffracts light emitted from a sample including a plurality of liquid components or a sample including a liquid component and a particle component when the sample is irradiated with irradiation light; and a detector that detects the light spectrally diffracted by the spectral optical system. The spectrometry device is further provided with: a sample cell that has a light incidence surface and a light emittance surface each having a property of transmitting light with a transmission wavelength or an absorption wavelength specific for the liquid components; a light irradiation means that irradiates, with the irradiation light, a sample in the sample cell through the light incidence surface; a standing wave forming means that forms a standing wave in the sample housed in the sample cell by irradiating the sample with ultrasonic waves; and a measurement optical system that is arranged between the sample cell and the spectral optical system and that converts the light emitted from the sample cell into parallel light.
従来技術、競合技術の概要(英語) BACKGROUND ART
And the onset of diabetes, the concentration of glucose in blood (blood glucose level) becomes abnormally high, for the treatment of diabetes and prevention of a health examination or the like, in various situations being measured blood glucose levels. Blood glucose levels can be measured by various methods, one of the specific absorption wavelength of glucose using Raman spectroscopic methods. Spectroscopic measurement method to a sample of a measuring object was irradiated with light having a predetermined wavelength range, thereby splitting the light emitted from the sample from the spectrum obtained to determine the glucose value.
Is blood (whole blood), plasma and cellular components in the liquid components of the red blood cells, white blood cells, platelets and the like, included in the plasma glucose. Both the cellular component is a fine, light is emitted into the whole blood and cellular components (especially red blood cells) and light scattering loss occurs. In such a scattering loss, light loss of the glucose (absorption loss) cannot be distinguished, the glucose concentration cannot be accurately measured. Therefore, the normal glucose concentration measurements, plasma or serum (coagulation of blood for the cellular components of the coagulation factor has been removed) is used. However, serum order to remove the plasma from the blood, or blood was centrifuged and the coagulation of blood for it is not necessary, to spectroscopic measurements take time and labor.
The above mentioned problem, rosacea Japan is performed in the manufacturing processes of, or ethanol contained in the liquor before filtration Japan when measuring the concentration of the components of the glucose and the like may occur. Japan (mash) pre-filtration is referred to as main fermenting mash rosacea, and water were added to the mother liquor were mixed in the tank, mold, into the steamed rice, made from the fermentation. Bubble opacified main fermenting mash of the high viscosity liquid and therefore, the spectral characteristics of glucose and ethanol contained in the main fermenting mash to be measured, the fermented wine base, Koji, such as steamed rice being affected by the light scattering particle component. By removing a particle component from the main fermenting mash of the particulate components described above can remove the effect of the, main fermenting mash was filtered to remove particulate components may still take time and labor work.
Incidentally, in the above fine particles of the particulate components from a sample containing components without, in the case of performing the spectral measurement that only the liquid component has been described in the problem, only the components of the fine particles also in the case of spectroscopic measurements is a problem.
