摘要： The present invention discloses a system for analyzing elements contained in a sample in very slight amounts, such as C, S, O, N, H and the like in materials, such as steel and ceramics. An element analyzer can gasify the sample elements in an appropriate gas, such as oxygen gas in a high-frequency heating furnace or an electric resistant furnace. Resulting gas can be introduced into a mass spectrometer to permit a quantitative analysis of the sample elements. A metal sample can be levitated and heated and melted with induction current for producing the resultant gas for introduction to a mass spectrometer.

摘要： An infrared microscopic spectrometer includes an optical system which allows for a shifting of the optical path interactive with a sample from a sample transmissive optical path to an optical path through an ATR crystal using ATR analysis. In the shown embodiment, the shift in the optical path is in a direction perpendicular to a transmissive optical axis, at least along a portion of the shift adjacent to the transmissive optical axis. The shift is undertaken by a moving means which moves the collecting element providing the infrared rays. A sample-holding structure allows the ATR crystal to be rotated or detachably removed, as necessary.

摘要： An infrared spectrometer disperses a radiation ray from a catalyst which has been exposed to a gas for evaluation to adsorb adsorbates thereon, and outputs spectral data in accordance with a wavenumber of the radiation ray to a computer storing reference data. The computer normalizes the spectral data and the reference data, and then, it calculates a product of the normalized spectral data and the reference data. Thereafter, a function of the product is differentiated with respect to the wavenumber to obtain a differential function. Accordingly, a specified wavenumber for which the differential function is zero is determined, so that the common peak of the spectral data and the reference data at the specified wavenumber is accurately determined.

摘要： A microscopic spectrometer having a separate optical path for masking light from a sample for spectrometric measurements. In the preferred embodiment, a beam splitter is disposed behind an object lens to form two branched optical paths. One of the optical paths is provided with masks at a point of focus along the path, allowing part of the image to be masked. The second optical path allows optical throughput and observation of the entire image. These two optical paths are rejoined, and a final image is obtained for visual inspection by synthesizing the two optical paths.

摘要： A microscopic spectrometer is disclosed wherein a sample can be irradiated with light from a first light source and either transmitted or reflected through the sample to a spectrometrical measuring system. A half mirror can be detachably provided in the optical system to form two branched optical paths. A second light source can be positioned to irradiate the sample 2 with light through a masking system. The half mirror can transmit the image of the masking system to superimpose it upon the sample and a composite image can then be reflected from the half mirror onto a branched optical path to be observed by the operator. The operator can adjust the actual positions of the masks assembly, while, at the same time, see the entire field of view of the specimen to therefore define in an easy and convenient manner the portion of the specimen to be tested. The respective half mirror and second light source can then be removed prior to performing a spectrometric measurement.

摘要： An analytical method capable of easily, rapidly, and accurately determining concentrations of a multi-component aqueous solution. Near-infrared spectra of a standard solution containing k components of known concentrations are measured n times within a range of 1,500 to 1,850 nm. A loading matrix of p columns by m rows and an intermediate matrix of k columns by m rows for an appointed factor number m are obtained from a response matrix of p columns by n rows consisting of p absorbance values of the respective spectra in a calibration stage and p absorbance values of a near-infrared spectrum within a wavelength range of 1,500 to 1,850 nm of a test liquid. The test liquid contains k components including pure water of unknown concentrations. The concentrations of the k components are determined from a group of absorbance values and the loading and intermediate matrices obtained in the calibration stage by a matrix operation in an prediction stage. In the calibration stage, k+1 characteristic contents can be obtained by adding a solution temperature as one of characteristic items, and k concentration values and one temperature value can be obtained in the prediction stage.
