Abstract
After a sampling needle is moved to a position above a sample container, the sampling needle is moved down so that the tip of the sampling needle penetrates a septum, and is then preferably moved down to a position at which the tip of the sampling needle is not brought into contact with a sample contained in the sample container, and then, the sampling needle is once elevated until the sampling needle is pulled out of the septum, and is then again moved down to penetrate the septum until the tip of the sampling needle is inserted into the sample to suck the sample through a suction port of the sampling needle, and then, the sampling needle is moved to a sample injection port of an analyzer to inject the sample into the analyzer.
