Abstract: An inspection system capable of making effective use of RFID (Radio Frequency IDentification) technology. The inspection system has first and second transport mechanisms. The first mechanism transports a sample holder holding a storage medium permitting writing, reading, and erasure of information from an analysis portion. The second mechanism receives the sample holder transported in by the first mechanism, injects an aliquot of a new sample into the holder, and then transports the holder to the analysis portion. Each of the transport mechanisms has writing means for writing at least one of (1) the identification number of the sample to be metered and injected as an aliquot, (2) information about metering and injection of sample, and (3) analytical information into the storage medium, as well as reading means for reading at least one of the three kinds of information (1)-(3) from the storage medium when the aliquot is analyzed.
