This operation has to be performed when the autosampler is installed on a GC.
Access sequence: RUN>SETTINGS>TRAY TYPE
In the “TRAY TYPE” screen you will see a list of the racks stored in the unit memory.
The racks are described by the number of vial positions, dimension of sample vials and needle
draw depth inside the sample vial (example: 42-10ml-20mm). Select the rack type to install. If
the rack is not shown in the tray list it has to be created (see paragraph 4.2.1.5 “Alignment:
Tray Install “).
A wizard for mounting the new rack/s starts. Follow it:
•
if necessary, remove the old rack (do not do this during autosampler installation);
•
install the new rack (see paragraph 7.9.1.1 “Rack mounting”);
•
Place a vial in the indicated position. Tap “Continue” to go on, otherwise “ABORT”;
•
The unit will ask to run the touch procedure. This can be run (recommended) or skipped.
7.9.1.1 Rack mounting
Place the rack in the tray paying attention that the letter A has to face toward the operator (see
figure below as example).
Warning
If the dimension of the sample vials has been modified (6ml-10ml-20ml) or if there is a modality
change (from Headspace/SPME to liquid mode and viceversa), the user has to install or remove
(if present) the spacers in the oven using the suitable tweezers (Spacers kits are sold as options,
see paragraph 1.7.2 “Options “). Select “Exit” to exit from the “TRAY TYPE” screen.
