PURPOSE: An atomic absorption analyzing device is provided to facilitate to draw a calibration curve having a high directivity as a light transmission distance is adjustable. CONSTITUTION: An atomic absorption analyzing device comprises a burner head(100), a rotary unit(200), a chamber(300), and a position determination unit. The rotary unit is arranged in the lower part of the burner head. The chamber supports the rotary unit. The position determination unit determines a rotating position of the rotary unit. The rotary unit includes a body(210) protruded from the bottom of the burner head. A hanging protrusion(220) is formed in the outer periphery of the body along a circumference direction. Gradations(A) are formed on the exterior surface of the body at a constant distance. |
