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： A sample disposed in a graphite tube in a furnace is subjected to thermal treatment at successive stages, drying, ashing and atomization and atomic absorption due to an element contained in the sample is measured. Amounts of inert carrier gas supplied to the graphite tube are different for different samples. The carrier gas flow rate at each of the stages is varied so as to reduce influences of background when each of the samples is treated. The carrier gas flow rate is varied, depending on the magnitude of a background signal measured on the basis of light which has passed through the graphite tube.

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.
