光分析用サンプリング装置。 In a sampling device that injects a sample into an electrothermal heating type nuclearization reactor for atomic absorption spectrometry analysis, a certain amount of electrolyte solution is discharged from the tip of the sampling nozzle within the range that the solution does not fall, and the nozzle descends from above the reactor. When the electrolyte solution at the nozzle tip and the atomization reactor come into contact, the change in electrical conductivity between the electrolyte solution in the nozzle and the atomization reactor is detected, and the position of the nozzle tip at this time is memorized and used for future samples. A sampling device for atomic absorption spectrometry, characterized by having a function of automatically discharging a sample at this storage position during an injection operation.
