Path of the i2000SR IM Carriers
The following is the path of the i2000SR IM carriers processed on
the IM.
1. During initialization, carriers are organized into two
queues (Routine and Priority) along Lane 3.
2. As soon as a sample tube is placed into the first carrier of
either the Priority or Routine position, it is routed from Lane 3 to
Lane 2. At the right end of Lane 2 is a gate and diverter that is
used to route the carrier to Lane 1.
3. At the entry to Lane 1, the tag reader reads the RFID and
the barcode scanner reads the label on the tube. The i2000SR IM
links the RFID and the scanned SID. The i2000SR IM sends the
i2000SR SCC the “prepare to sample” message.
4. After carriers are released from the barcode gate they are
routed to the i2000SR STAT pipetting location. The i2000SR IM
sends the i2000SR the SID. The i2000SR performs a host query
and, if the sample has a STAT test assay, the i2000SR STAT
pipettor will aspirate the required volume for each assay to be
processed.
5. After the last aspiration of the STAT assay, the carrier is
released and routed to the i2000SR routine sample pipettor. As
the carriers enter the sample pipettor aspiration point, the
i2000SR IM sends the SID to the i2000SR. The i2000SR performs
a host query and if the sample has a routine assay test ordered,
the i2000SR sample pipettor aspirates the required volume for
each assay to be processed. After the last aspiration, the carrier is
released and routed to the gate at the end of Lane #2.
6. The carrier RFID is read. As the carrier is from the IM, the
carrier is rerouted to Lane 4.
7. Lane 4 is used to manage a queue to re-supply off-line
carriers to the Routine and Priority queues on Lane 3.
Input and Output Areas
The IM offers three areas for manual operation with a total of 21
available carriers arranged in the following order after IM
initialization:
• Priority sample input area with 6 Priority Carriers (A).
• Routine sample input area with 11 Manual Carriers (B).
• Sample output area with 4 Output Carriers (C)
The IM carriers, identified as Off-line Carriers, are gray in color
differentiating them from the black ones used on the Workcell.
The Off-line carriers have different RFID tags than those on the
Workcell. The IM reads the RFID and ensures that the Off-line
carriers are never routed into the Workcell.
