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 first sample
to the last sample position will be run. Therefore the last sample must be equal or higher
than the first sample;
•
Cycle(s): the number of times that the same sample has to be injected;
•
Internal Standard: the sample vial (or solvent vial) to use as the Internal Standard.
•
Pre Wash Solvent: the solvent to use for the pre-washing operations. This can be a
single solvent vial (e.g.: “A”) or a combination of 2 solvents (e.g.: “A+B”). If 2 solvents are
used it will wash with the first solvent and then wash with the second solvent;
•
Post Wash Solvent: the solvent to use for the post-washing operations. This can
be a single solvent vial (e.g.: “A”) or a combination of 2 solvents (e.g.: “A+B”). If 2
solvents are used it will wash with the first solvent and then wash with the second
solvent;
•
Injection Mode: can have one of the following values:
Default
Uses the injection port defined in the Setup (see paragraph 4.2.6.3 “Setup
Front
Rear
only in the second injector
Confirmation
It injects the same sample in both front and rear injectors (see paragraph
11Appendix A – Glossary”)
High
throughput
It injects different sampler alternatively in front and rear injector (see paragraph
•
Name: shows the name of the sequence
step. Tap “Exit” to exit from the “STEP X” screen.
If any parameters have been changed a confirmation screen appears “Modifying sequence step
X”. Tap “SAVE” to save the modifications or “CANCEL” to exit without saving.
The display return to the “RUN: SEQUENCES” screen.
6.2.2.1 High throughput mode
In this mode the injections are performed alternately in the two injectors start from the
front injector. So it will inject the first vial of the step in the front injector, the second vial of the
