Abstract: The present invention provides a flame atomic absorption photometer including a burner 110 configured to form a flame by burning a mixture of a mixed gas of a fuel gas and a combustion-assisting gas and a nebulized sample liquid, flame light detection units 181 and 182 configured to detect light radiated from the flame, and a ceased flame determination unit 162 configured to determine that the flame has ceased when the intensity of the light detected by the flame light detection unit is lower than a predetermined threshold value, wherein the flame light detection unit is configured to selectively detect light having a wavelength of 290 nm or more and 330 nm or less.

Abstract: A flame atomic absorption spectrophotometer in which an angle of a burner can be manually adjusted and a rotation position of the burner can be easily obtained is provided. An atomization unit burns mixed gas of fuel gas and supporting gas with a burner to form flame, and atomizes a sample by spraying the sample into the flame. Alight source emits a measuring beam into the flame. A detector detects the measuring beam that has passed through the flame. A manual rotation mechanism allows the burner to be manually rotated to change an angle of the burner with respect to an optical path of the measuring beam. A rotation position detection unit detects a rotation position of the burner.

Abstract: The invention relates to a tube furnace device for an atomizing furnace and to an analyzing apparatus comprising an atomizing furnace and a tube furnace device, in particular for atomic absorption spectrometry, the tube furnace device comprising a sample carrier means (11) and a bearing means (12) for supporting and forming electrical contact with the sample carrier means, the sample carrier means having a receiving tube (16) forming a tubular receiving space (17) for receiving an analyte, the sample carrier means having two bearing protrusions on the receiving tube for forming a connection with the bearing means, the bearing protrusions extending perpendicularly, preferably orthogonally, in relation to a longitudinal axis of the receiving tube, wherein the tube furnace device has a contact pressure means (13) via which a contact pressure force (14) can be exerted on the bearing protrusions in the direction of a passant line (20) in relation to a circular cross section (21) of the receiving tube.

Abstract: An atomization unit has a tube-shaped furnace, and heats and atomizes a sample injected into the furnace. A light source unit emits light having a wavelength to be measured toward the atomization unit such that light passes through the furnace. An optical system transmits the light having the wavelength to be measured, of light passing through the furnace. A detection unit detects the light transmitted by the optical system. A light transmission plate is provided at a position in an optical path of the light passing through the furnace toward the detection unit, to obliquely cross an optical axis of the light. An image capturing unit is arranged outside the optical path, and captures an image inside the furnace by receiving light reflected by the light transmission plate, of the light passing through the furnace.

Abstract: A flame atomic absorption spectrophotometer in which an angle of a burner can be manually adjusted and a rotation position of the burner can be easily obtained is provided. An atomization unit 12 burns mixed gas of fuel gas and supporting gas with a burner 121 to form flame, and atomizes a sample by spraying the sample into the flame. Alight source emits a measuring beam into the flame. A detector detects the measuring beam that has passed through the flame. A manual rotation mechanism (such as a gripper 124) allows the burner 121 to be manually rotated to change an angle of the burner 121 with respect to an optical path P of the measuring beam. A rotation position detection unit 125 detects a rotation position of the burner 121.

Abstract: The atomic absorption spectrophotometer is provided with an atomization unit, a light source, a detector, an optical system, a camera, and a captured image data storage unit. The atomization unit has a tube-like furnace and atomizes the sample injected into the furnace by heating the sample. The light source emits light of a wavelength of a measurement target toward the atomization unit so that the light passes through the furnace. The detector detects the light passed through the furnace. The camera captures an image of an inside of the furnace before performing a measurement process in which a sample is atomized in the furnace and its absorbance is measured. The captured image data storage unit stores the captured image data obtained by capturing the image by the camera in association with the measurement data corresponding to the captured image data.
