Optimizing Performance
Precise Injection Volume
Eject Speed
The default eject speed setting is 400 μL/min. When using large injection
volumes, setting the eject speed to a higher value speeds up the injection cycle
by shortening the time the metering unit requires to eject solvent at the
beginning of the injection cycle (when the piston returns to the home
position).
An EJECT statement in an injector program also uses the eject speed setting
which is configured for the autosampler. A faster eject speed shortens the time
required to run the injector program. When using viscous samples, a high eject
speed should be avoided.
