0–15 This parameter allows to set the number of plunger
strokes to eliminate air bubbles forming during the
sample withdrawal.
A, B, C, D, This parameter allows to select the vial, or
A+B, combination of two vials, containing the washing
C+D solvent.
0–15 This parameter allows to set the number of syringe
pre-washings with the selected solvent.
A, B, C, D This parameter allows to select the vial, or
A+B combination of two vials, with the washing solvent.
C+D
0–15 This parameter specifies the number of syringe
post-washings with the solvent selected.
Yes, No This parameter sets the sample drawing speed from
the vial as a function of the sample viscosity.
Select No (default value) if the sample has low
viscosity.
Select Yes when the sample has high viscosity.
Bottom, Center, This parameters sets the penetration depth of the
selectable in the syringe needle into the vial.
sub-menu
If Bottom (default value) is selected, the needle
goes down to the vial bottom.
If Center is selected, the needle goes down to half
vial.
Standard, Minimum, This parameter defines the penetration depth of the
selectable in the syringe needle into the injector.
sub-menu
If Standard (default value) is selected, the needle
goes down to the maximum allowed depth.
If Minimum is selected, the needle enters the
injector and stops immediately beyond the septum
(Cold Needle Technique).
0–63 sec This parameter specifies how long the syringe
needle must remain in the injector before injection
(Hot Needle Technique).
0–63 sec This parameter specifies how long the syringe
needle must remain inside the injector after
injection.
