摘要： A spectrophotometer includes a xenon flash lamp, a spectroscope, and a light detector, wherein the spectrophotometer is configured to arrange a low-pressure mercury lamp on a bundle of light rays between the xenon flash lamp and the spectroscope on an as needed basis upon a performance determination of the spectrophotometer, and has a shutter mechanism that switches between shielding the bundle of light rays emitted from the low-pressure mercury lamp and allowing the bundle of light rays to pass through. A processing unit determines the performance of the spectrophotometer by detecting each of the light intensities with the light detector at the time when shielding the bundle of light rays and at the time when allowing the bundle of light rays by operating the shutter mechanism.

摘要： Provided are a spectrophotometer using a xenon flash lamp and which can compare with data stored in the past, and a method for determining the performance of the spectrophotometer. In normal times, spectroscopic analysis is performed by employing a bundle of light rays emitted from the xenon flash lamp, spectrally separating the bundle of light rays into arbitrarily-defined wavelengths with a spectroscope through a concave mirror, and detecting the bundle of light rays having passed through a sample with a photodetector. When the performance is to be determined, a low-pressure mercury lamp is arranged in a path of the bundle of light rays between the xenon flash lamp and the spectroscope, a light-shield plate which constitutes a shutter mechanism is operated to shield the light and allow the light to pass through, and the intensity of the light is detected, to thereby determine the “wavelength accuracy” or the “resolution” by employing the bright-line spectrum of the low-pressure mercury lamp. Thus, spectroscopic analysis can be performed while allowing to compare with data stored in the past to be made.

摘要： A transparent or translucent column is used for an analytical method for quantifying hexavalent chrome in a liquid sample. The method includes adding a reagent for complex formation to a liquid sample to form a colored chelate of hexavalent chrome, adding a salting-out agent to the liquid sample, then contacting the liquid sample which an adsorbent, and measuring a thickness of a colored layer of the adsorbent. The column is filled with a mixture of the adsorbent and glass wool, and provided with a scale on the side, thereby allowing a thickness of a colored layer of the adsorbent to be read from outside.
