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 5.3
“HT2000H/HT2000HT: 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 posi
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” (see paragraph
5.3 “HT2000H/HT2000HT: Sequence”) to the last vial position in the rack (G.6 for
HT2000H/HT2000HT, see paragraph 2.1.1.2 “HT2000H/HT2000HT 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.
Select “Start Automatic run” to start the automatic run.
During the automatic run, a screen (“AUTOMATIC RUN EXECUTION”) displays status information.
