PROBLEM TO BE SOLVED: To prevent the generation of spike noise so as to secure stability of analysis by arranging an inner tube so that its center line is positioned below the center line of a spray chamber in compliance with a nebulizer in which a spray hole is positioned below the center of the tip face. SOLUTION: In an atomization introducing device 5, in compliance with a nebulizer 50 in which a gas discharging port serving as a spraying hole is positioned below the center of the tip face, an inner tube 51A is arranged so that the center line C51 of the inner tube 51A is arranged below the center line C of a spray chamber 51, that is, so that the center line C51 of the inner tube 51A is matched with the gas discharging port. Through a mounting hole 52a in an end cap 52, the nebulizer 50 is installed. A sample to be measured is atomized by means of gas jetted from the gas discharging port and is sprayed in the center line C51 direction of the inner tube 51A, so that almost all the mist sprayed from the nebulizer 50 is introduced into the inner tube 51A and a direct mist penetration phenomenon into an outer tube 51B is eliminated, and as a result, generation of spike noise and the like can be prevented. |
