AS 8000 Autosampler . 65
•
The light switch sensors by the furnace hole detect the presence of a sample pan or
furnace lid being placed in the furnace hole. If the autosampler is supposed to be
removing a lid, for example, and the gripper fails to pick up the lid, it is detected by the
sensors and an error message is displayed.
• The autosampler is fully automated and controlled by the software. The two-piece
sample tray holds up to 45 samples for efficient unattended operation.
One tray holds 22 samples and the other 23 samples. This difference means that you
cannot mistakenly place one tray in the wrong position. The trays have recesses on the
bottom which catch positioning pins in the base plate. The positioning pins for one tray
are located in different places than those for the other tray, which also prevents one
tray from being inserted into the wrong location.
The trays can be removed independently so that you can load one with fresh samples
while the autosampler runs samples in the other. You could also add samples to the
tray “in use” to replace samples that are completed by pausing the play list.
The Pyris Player feature allows for creation of sequences or play lists to operate the
autosampler and instrument. During an autosampler sequence, you can perform multiple
experiments, curve optimization, calculations, and printing. With Pyris Player, you can create
Sample Groups that group similar analyses together to be run in any order. See the Software
help for details.
