This function can only be activated during the sample conditioning. When this option is activated,
the autosampler stops the current sample conditioning and replaces the sample to its original
position of the tray without injecting it.
The autosampler will re-start the automatic injection procedure from the point of interruption.
7.3.4 Priority injection
Only for Liquid mode.
While an automatic run is in progress, an unscheduled sample may need to be processed
immediately – this can be performed using the Priority injection function. This function can be
used to make an injection from any vial position and using any available injection method.
During the automatic run, the “AUTOMATIC EXECUTION SCREEN” is displayed (see paragraph
“Automatic run“). Then follow the access sequence: AUTOMATIC EXECUTION
SCREEN>MENU>PRIORITY INJECTION
Depending on the autosampler status (whether the next sample injection is already in progress
or not) you may be required to wait up to few minutes before programming a priority injection.
This ensures the integrity of the analytical data.
Use the wizard to insert the vial for the priority injection when the tray is in the open position.
Then tap “OK” to allow tray to close. A screen will appear to allow the priority injection
parameters to be set, as follow:
•
Mandatory:
•
Method: (from 0 to 9);
•
Sample: the vial position of the sample to be injected (e.g.: A.2);
•
Optional (if required by the selected method):
•
Internal Standard: vial position of the internal standard (e.g.: B.5) -
•
Pre Wash Solvent: solvent to use for the pre injection wash
•
Post Wash Solvent: solvent to use for the post injection wash
Then select “Start Priority” to run the priority injection. During the priority injection, a screen will
show status information. Tap “STOP” to stop the procedure. Tap “ABORT” to confirm and
“RESUME” to continue operation as before.
Select “Exit” to exit from the screen for priority injection without running it.
Once the priority injection has been made the autosampler will re-start automatic injection
procedure from the point of interruption.
