6 Programming Sequence
6.1 Sequence: Headspace mode
6.1.1 Sequence Menu
This function is used to edit a sample list (later refered to as Sequence).
Access sequence: RUN>SETTINGS>SEQUENCES
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 6.1.2 “Setting
sequence step parameters “).
Select “Tools” to access to the “SEQUENCE TOOLS” screen (see paragraph 6.1.3 “Sequence
tools”).
Tap “Exit” to exit from the “RUN: SEQUENCES” screen.
