PROBLEM TO BE SOLVED: To obtain an atomic absorption photometer reduced in its installation area, constituted so as to facilitate the highly precise adjustment of an automatic sampler and easy in maintenance.;SOLUTION: A lamp chamber 2, a graphite oven analyzing part 3, a flame analyzing part 4 and a flame gas control part 51 are successively arranged in a main body housing 1 from the right-hand side and the automatic sampler 6 is arranged above the lamp chamber 2. A power supply part for supplying power required by the graphite oven analyzing part 3 and the whole of the photometer, a power supply part having a space for a substrate for housing a control substrate for controlling the whole of the photometer and a control substrate housing part 71 are arranged on the back surface side of the lamp chamber 2, the graphite oven analyzing part 3, the flame analyzing part 4 and the flame gas control part 51. The automatic sampler 6 has a square sample tray and is constituted so as not only to drive an arm for holding a suction needle in a lateral direction and an up and down direction but also to drive the sample tray in a depth direction to select a sample.;COPYRIGHT: (C)2004,JPO&NCIPI
