PURPOSE:To enable the setting of a sample introduction tube and a sample discharge tube on a specimen sampling bottle in multiple passages, by fixing the specimen sampling bottle or the like while a syringe is moved. CONSTITUTION:A plurality of online liquid specimen sampling bottles 1 and waster liquor bottles 2 are arranged with injection ports thereof set securely to an analyzer and a specimen sampling syringe 4 is moved to the positions of the injection ports to the bottle 1, the bottle 2 and the analyzer. Then, the syringe 4 and a syringe plunger are moved vertically to clean up the syringe 4, sample a specimen from the bottle 1 and inject the specimen to the analyzer. Here, to move the syringe 4 to the positions of injection ports of the bottle 1, the bottle 2 and the analyzer, a photosensor is used to check the positions of the bottle 1 and the like and then, the syringe 4 is lowered. This enables the confirmation of correct positions thereby reducing the breakage of a syringe needle. |
