    摘要: The invention intends to provide an atomic absorption spectrophotometer which can establish a uniform heat distribution during heating of a sample and can improve analysis accuracy and analyzing efficiency. For this purpose, a graphite tube type cuvette mounted in a graphite atomizer furnace for an atomic absorption spectrophotometer comprises a large-diameter portion for retaining a sample in place, a small-diameter portion connected to the large-diameter portion and having a smaller diameter than the large-diameter portion, and a step portion for demarcating between the large-diameter portion and the small-diameter portion. The graphite tube type cuvette is formed such that its cross-sectional area in a plane perpendicular to the direction of passage of an electric current supplied to the cuvette is the same in any of the large-diameter portion, the small-diameter portion and the step portion. The amount of resistance heat is thereby also the same in any portions.

    摘要: In a spectrophotometer of the single-beam type, highly stable transmission and absorption spectra can be obtained with a high SNR while drifting is suppressed and for a long time even when the amount of light from the light source is varied over time. The spectrophotometer includes: a light source; a sample cell; a polychromator that generates a transmission spectrum of a sample in the sample cell by dispersing a portion of light from the light source that has passed through the sample into a plurality of spectral components; an image sensor that detects the transmission spectrum of the sample; a light source monitoring photodetector that detects a portion of the light from the light source that has not passed through the sample cell; and an operation unit that corrects the transmission spectrum of the sample by using an output signal from the light source monitoring photodetector.

    摘要: A light beam emitted by a hollow cathode lamp is concentrated on a central portion of an electrothermal sample atomizing apparatus by a concave mirror. The light concentrated on the central portion of the electrothermal sample atomizing apparatus is further concentrated on a central portion of a flame produced in a burner type sample atomizing apparatus by a lens. The light traveled through the burner type sample atomizing apparatus is condensed by a concave mirror, reflected by a flat mirror, and concentrated on an entrance slit of a spectroscope. Light outgoing through an exit slit of the spectroscope is detected by a photodetector.
