The Draw Speed determines the rate at which the plunger draws sample from the vial. Set the speed to an appropriate value for your sample. For viscous samples, use a slow Draw Speed.

The Eject Speed determines the rate at which the plunger ejects sample from the metering device. If you are injecting large volumes of sample, setting a high Eject Speed will shorten the time needed for an injection cycle. For viscous samples, use a slow Eject Speed.
See Draw Speed above
The Draw Position is a vertical offset that enables you to position the needle a specific distance (in mm) away from its standard position. The Draw Position offset is calculated from the bottom of the vial, with a slight amount of clearance to cover tolerances. Use a negative offset to touch the vial bottom with the needle. Use a positive offset to raise the needle higher in the vial to clear precipitates on the bottom of the vial, or to select one phase of a biphasic sample.

The default position (Draw Position = 0.0) is a vertical offset of +2.0 mm. |
