摘要： PROBLEM TO BE SOLVED: To discriminate the material of waste plastic material more accurately. SOLUTION: A light receiving part 6 is arranged over a measuring position, and a light source 8 for transmission measurement is arranged on the opposite side of the light receiving part 6 relative to the plastic material 4 placed on the measuring position, and irradiation light from the light source 8 is transmitted through the waste plastic material 4 and enters the light receiving part 6. Light sources 10 for reflection measurement are arranged on the same side as the light receiving part 6, and irradiation light from the light sources 10 is reflected by the waste plastic material 4 and enters the light receiving part 6. The light receiving part 6 detects both transmitted light and reflected light simultaneously. The detection signal is taken into a detector body 12, and transmitted to a personal computer 14 for operation after being amplified and A/D converted, to thereby execute material discrimination.

摘要： PROBLEM TO BE SOLVED: To provide a concentration determining method excellent compared with conventional one by paying attention to absorption in a solvent. SOLUTION: An absorbance is found from a spectrum of a glucose solution by using as a measuring wavelength a wavelength of 1407 nm wherein water has absorption and glucose has no absorption, and using a wavelength of 1300 nm as a reference wavelength, so as to find a correlation of a glucose concentration therewith. The absorbance of the water in linearly decreased along with increase of the glucose concentration as a result thereof. Glucose is thereby determined quantitatively by measuring the absorbance at the absorption wavelength of water that is the solvent, using the result as a working curve.

摘要： PROBLEM TO BE SOLVED: To improve the quantitative accuracy of the body fat percentage. SOLUTION: A photometric device 2 comprises a light flooding mechanism to irradiate the infrared ray included in the wavelength domain of 1.1 to 2.0 μm on an animal, a light receiving mechanism to receive the output light from the animal caused by the irradiated light, and a spectrometric means for the irradiated light onto the animal or the output light from the animal, and measures the absorbance at the specified wavelength by the animal. A compression mechanism 4 can compress a location to be measured of the animal or its peripheral location, and a differential absorbance calculating means 6 calculates the differential absorbance from the first absorbance by a photometric device 2 under the compressed condition by the first pressure by the compression mechanism 4 and the second absorbance by the photometric device 2 under the compressed condition or the non-compressed condition by the second pressure lower than the first pressure. A storage part 8 stores the relationship between the body fat percentage and the differential absorbance, and an operation part 10 measures and outputs the body fat percentage based on the relationship stored in the storage part 8 from the differential absorbance calculated by the differential absorbance calculating means 6.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring concentration of component to be measured by which the concentration of a component to be measured in a sample solution containing the component and its interfering component can be measured quickly and accurately. SOLUTION: At the time of measuring the hydrogen peroxide concentration of the sample solution, a concentration-reduced sample solution is prepared by keeping the sample solution in a decomposing tank 4 for a fixed period of time while the solution is vibrated by means of a vibrating motor 6. A spectroscopic analyzer 8 measures the intensity Is of an ultraviolet ray transmitted through the sample solution after the ray is radiated at a prescribed intensity and the intensity Ig of the ultraviolet ray transmitted through the concentration- reduced sample solution after the ray is radiated at the prescribed intensity. Then the hydrogen peroxide concentration of the sample solution is computed quickly and accurately without being affected by the interfering component by utilizing the proportional relation between -log (Is/Ig) and the hydrogen peroxide concentration.

摘要： PROBLEM TO BE SOLVED: To provide a means which enables high accuracy biological information with little variation to be measured as it can hold constant the relative positions of an optical biological information measuring device and a living body when the biological information is measured using the device. SOLUTION: An optical biological information measuring device is provided with a positioning device fixing or positioning a hand 2 in a predetermined measuring position on a temperature adjustment plate 1. In the positioning device, the wrist is clamped and secured by a notched ring 30 for the wrist, and the fingers are clamped and secured by notched rings 3135 for the fingers, the rings preventing horizontal displacement of the hand 2. Further, the longitudinal displacement of the hand 2 is prevented by means of abutting poles 36-38 which abut to the roots of the fingers. Thus, the part to be measured of the hand 2 is positioned at a certain position relative to a detection element 3, and high-accuracy biological information with little variation can be measured.

摘要： PROBLEM TO BE SOLVED: To provide a means capable of holding constant the pressure on the part for measurement when measuring biological information using an optical biological information measuring device and of enhancing the intimateness between the part for measurement and a detection terminal. SOLUTION: An optical biological information measuring device, when measuring biological information about the part for measurement which is a part of the palm of a hand 2 placed on a temperature adjustment plate 1, causes the part of the back of the hand located above the part for measurement to be pressed downward via a balloon 22. Then the pressure on the back of the hand is adjusted to a preset certain value according to the value indicated on a pressure gauge 23. The pressure on the part to be measured is thereby hold constant. Also since the hand 2 (back of the hand) is pressed downward, the intimateness between the part for measurement and a detection terminal 3 is enhanced.

摘要： PROBLEM TO BE SOLVED: To precisely measure the IPA concentration in an aqueous solution containing a very small amount of IPA. SOLUTION: Light of a beam 6a is reflected by a dichroic mirror 10 to introduce only the light of a short wavelength band having a wavelength shorter than 200 nm into the aqueous sample solution in a cell 2. The light in a short wavelength side having a wavelength shorter than 190 nm out of the light is absorbed by water in the sample solution, only the light in a wavelength band of 190-200 nm is reflected by total refrectance mirrors 14a, 14b to be transmitted again through the sample solution in the cell 2, and the light is converged by a lens 16 in a detector 18 to be detected. The light is absorbed therein by the IPA in the sample solution. A reference beam expressing light source intensity not affected substantially by the absorption of the IPA by the light reflected by a reflection mirror 12 of the beam 6b is measured to determine the IPA concentration in the aqueous sample solution based on a difference (differential absorbance) therebetween.

摘要： PROBLEM TO BE SOLVED: To enhance the discrimination accuracy of a plastic material and other samples. SOLUTION: Data are extracted from the absorbing spectrum of a sample (step S1) and two data among preliminarily registered reference data are read (step S2) to compare two data to judge either one of two data to which the sample spectrum data are near, to select the nearer one (step S3). Next, one of the remaining reference spectrum data is read (step S5) and the sample spectrum data is compared and judged with respect to the read data and the previously selected reference spectrum data and the nearer data among two reference spectrum data is selected (step S3). This comparing and judging operation is repeated until the remaining reference spectrum data are exhausted (step S4) and one finally selected to be near to the sample spectrum data is judged to be the material of the sample to be outputted (step S6).
