Pre wash solv
A, B, C, D, AB,
CD This parameter specifies the solvent vial used for
washing prior the injection.
Pre wash cycles
0–15 times This parameter specifies the number of times the
syringe is pre-washed with solvent.
Post wash solv
A, B, C, D, AB,
CD This parameter specifies the solvent vial used for
washing after the injection.
Post wash cycles
0–15 times This parameter specifies the number of times the
syringe is post-washed with solvent.
Viscous sample
No–Yes Set No for no viscous or low viscous sample.
Set Yes for high viscous sample.
Sampl. Depth
Bottom–Center Set Bottom to pull-up the liquid from the bottom of
the sample vial.
Set Center from half height of the sample vial
Inj. Depth
Standard–
Minimum It determines the penetration depth of the syringe
needle into the vial.
When Standard is set (default value) the syringe
needle penetrates into the injector up the maximum
depth limit (Hot Needle Technique).
When Minimum is set, the syringe needle
penetrates into
the
injector up to go beyond the
septum only (Cold Needle Technique)
Pre dwell time
0–630 seconds This parameter specifies how long the needle
remains inserted without injecting for a hot needle
injection (only in Standard mode)
Post dwell time
0–630 seconds This parameter specifies how long the needle
remains inserted after injection (only in Standard
mode.
