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.

Claims

1. An inspection system having a first transport mechanism for forwarding a sample holder fitted with a storage medium permitting writing, reading, and erasure of information from an analysis portion and a second transport mechanism for receiving the sample holder forwarded from the first transport mechanism and transporting the holder to the analysis portion after a new sample is metered and injected as an aliquot into the holder, wherein each of said transport mechanisms comprises:

writing means for writing at least one of three kinds of information comprising (1) an identification number given to the sample to be metered and injected, (2) information about metering and injection of sample, and (3) analytical information when the sample is metered and injected as an aliquot; and

reading means for reading at least one of the three kinds of information (1)-(3) from the storage medium when the sample aliquot is analyzed.

2. The inspection system of claim 1, wherein said storage medium is an RFID chip.

3. The inspection system of claim 1, wherein said writing means is an RFID antenna.

4. The inspection system of claim 1, wherein said reading means is an RFID antenna.

5. The inspection system of claim 1, further comprising erasing means for erasing information in the storage medium fitted in the sample holder prior to metering and injection of the sample.

6. The inspection system of claim 1, wherein said erasing means is an RFID antenna.

7. The inspection system of claim 1, further comprising a third transport mechanism for receiving the sample holder and transporting it very close to the analysis portion after the holder is transported in by the second transport mechanism.

8. The inspection system of claim 7, wherein said third transport mechanism is fitted with second reading means for reading at least one of the three kinds of information from the storage medium.

9. The inspection system of claim 8, wherein said second reading means is an RFID antenna.

10. The inspection system of claim 1 or 7, further comprising a fourth transport mechanism for transporting the sample holder for reinspection.

11. The inspection system of claim 10, wherein said fourth transport mechanism is fitted with third reading means for reading at least one of the three kinds of information from the storage medium.

12. The inspection system of claim 11, wherein said third reading means is an RFID antenna.
