Select “Start Injection/Single Run” to perform the single injection. During the single injection, the
status information is displayed. Tap “STOP” to stop the procedure and then “ABORT” to confirm or
“RESUME” to continue the single injection procedure.
Select “Exit” to exit from the “Single Injection” screen and return to the home screen.
7.3 Automatic run
This function is used to carry out a sequence of injections from different sample vials. Access
sequence: RUN>AUTO RUN.
In the “Automatic Run” screen you need to define the following parameters:
•
First step: sets the first step of the sequence;
•
Last step: sets the last step of the sequence;
It is only possible to select existing steps: numbers corresponding to non-existent steps
will not be displayed. To set-up or modify a sequence please refer to paragraph 6
“Programming Sequence“. The Last Step must be equal to or greater than the First Step:
for example if you set the “First step” as “5”, the last step must be “5” or higher (6-7-8-9
etc...).
•
Run-All-Samples: select one of the following values:
Yes
“Run-All-Samples” function is active: after two empty positions
on the rack, the autosampler will stop and will not continue with
the other vials set in the sequence
No
“Run-All-Samples” function is not active: after two empty
positions on the rack, the autosampler will not stop and will
continue looking for the other vials in the sequence
The “Run-All-Samples” function can be used to run a lower set of samples than normal
without having to program a separate sequence. In the sequence step, set the “Last vial”
to the last vial position in the rack (see paragraph 2.1.1.1 “HT2800T/HT2850T
Sample rack“), even if there are fewer samples. If the “Run-All-Samples” function is active
(select “Yes”) and the run is started, then the autosampler will process all the samples
available, and after detecting two empty positions it will automatically stop. This option
allows the operator to always use the same sequence of steps (without needing to
change the first and last vials every time), even if the number of samples to process
changes from time to time.
