• Start: the autosampler will run all the stored sequence steps (see paragraph 7.6)
processing all the vials set in each sequence step (note that after detecting two empty
positions it will automatically stop).
• Fiber Cleaning Conditioning: conditions or cleans the Fiber (see paragraph 7.6);
• Load Sample Tray: opens the tray to load/unload the samples (see paragraph 7.7);
• Settings: accesses other autosampler functionalities and menus (see paragraph 7.9).
• Change mode: to change the current autosampler mode (Headspace, Liquid, SPME)
(see paragraph 7.10).
Tap one of these options to enter the respective sub menu.
To move to the standard User Interface, see paragraph 4.2.6.3 “Setup configuration: Run”.
7.2 Single injection
This function is used to carry out one or more injections from a single vial.
Access sequence: RUN>SINGLE INJECTION.
In the “Single Injection” screen you need to define the injection parameters:
• Method: (from 0 to 9);
• Sample: the vial position of the sample to be injected (e.g.: A.2).
In Liquid mode there are also some optional parameters to be set if required by the selected
method:
• Internal Standard: the vial position of the internal standard (e.g.: B.5);
• 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 two solvents
are used it will wash with the first solvent and then wash again 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 two solvents
are used it will wash with the first solvent and then wash again with the second solvent.
In SPME mode there are also some optional parameters to be set if required by the selected
method:
• Derivatizer: specifies the derivatizer position (see derivatization in paragraph 11
