PURPOSE:To simplify the operation and the equipment by automatically introducing a sample into an analyzer from one or a plurality of micro syringes into which a constant amount thereof is charged. CONSTITUTION:A micro syringe is composed of a cylinder 1, a plunger 2 and a needle 3 and the plunger 2 is driven forward or backward to suck or discharge a sample through the needle 3. The micro syringe into which the sample is sucked and charged is set on a syringe base 4. By a command of a controlling section 8, a micro syringe driving section 5 pushes the whole of the micro syringe toward an analysis meter 7 and the needle 3 is stuck into a sample injection port 6. Then, as the plunger 2 is pushed with a plunger driving section of the micro syringe driving section 5, the sample is injected into analysis meter to analyze. Upon the end of the analysis, the syringe base 4 is moved for injection of the subsequent sample from the micro syringe. |
