The sequence is a program (a list of instructions) that defines a series of injections also know as
an Automatic Run (see paragraph 7.3 “Automatic run”). The program has 16 steps (1 to 16).
Each step defines different parameters involved in the injection cycle (tray type, method, first
sample, last samples, cycles etc..). Each step can work alone or with other steps (see para 7.3
“Automatic run”).
The “RUN: SEQUENCES” screen displays the sequence steps stored in the autosampler memory.
The steps can be identified by the number or by a name.
The name can only be created or edited using a PC. Once the names have been created, they will
be visible on the touch screen.
Select a step number/name to enter the “STEP X” screen (X is a number from 0 to 16, that can be
followed by the step name) to view or edit the parameters. See paragraph 6.3.2 “Setting sequence
step parameters “).
Select “Tools” to access to the “SEQUENCE TOOLS” screen (see paragraph 6.3.3Sequence
tools6.3.3 “Sequence tools“).
Tap “Exit” to exit from the “RUN: SEQUENCES” screen.
6.3.2 Setting sequence step parameters
This screen is used to display or edit a sequence step.
Access sequence: RUN>SETTINGS>SEQUENCES>STEP X
In the “STEP X” screen, the following parameters are available:
•
Tray type: specifies the type of tray to use;
•
Method: specifies the method to be used;
•
First Sample: specifies the number of the first vial to run;
•
Last Sample: specifies the number of the last vial to run; all the vials from the
first sample to the last sample position will be run. Therefore, the last sample must
be equal to or higher than the first sample;
•
Derivatizer: specifies the derivatizer position (see derivatization in paragraph 11
“Appendix A – Glossary“).
•
Desorption Mode: can have one of the following values:
Default
Uses the desorption mode defined in the Setup (see paragraph 4. 2.6.3
“Setup configuration: Run “)
