PURPOSE:To automate positional adjustment of a gas burner, by providing the gas burner with a moving means to control the moving means so that an absorption signal attains the max. value. CONSTITUTION:A burner 3 is set with a CPU at a reference position where a luminous flux thereof 3 passes the center of a flame 2 parallel with the length of the burner 3. The burner 3 is driven longitudinally by a burner position driver 8 from the position while the longitudinal position of the burner 3 and a data of an absorbance signal from an absorbance measuring circuit 7 are stored into the CPU. The CPU set the longitudinal position of the burner 3 to maximize the absorbance. Then, the burner 3 is moved vertically at the longitudinal position to be set at such a height as to maximize the absorbance. Moreover, the burner 3 is turned in place to be set at such an angle as to maximize the absorbance. In this manner, the CPU controls the device 8 to ensure the maximum of the absorbance signal of the circuit 7. This enables the automation of the positional adjustment of the burner 3 to make an operator free from complicated burner position adjusting operation thereby achieving a higher analysis efficiency.
