checks again for the
presence of the “Ready”
signal from the analyzer and

• Clean mode: only for SPME mode. It sets the predefined clean mode. In HT2800T this
parameter is editable only if the system is configured for two injectors. This setting is
used for single injection runs and automatic run.
Clean Mode
Front: the Fiber cleaning is performed in the first injector
Rear: the Fiber cleaning is performed in the second injector
Cleaning Device: the Fiber cleaning is performed in the SPME Fiber
Cleaning Devive location (indicated with number 7 in Figure 1). This option
is available only in HT2850T.
• Shaker speed. It sets the speed of the shaking (only in Headspace and SPME mode).
• Empty Position Synchro. It sets the autosampler behaviour when a vial is missing (only
in Liquid mode). It may have the following values:
Empty
Position
Synchro
Yes: If a vial is missing, the autosampler emits the “Start” signal to the
analyzer
“as
if
the vial
were
present”.
No: If a vial is missing, the autosampler does not emit the “Start” signal to
the analyzer and skips directly to the next vial.
