Optimizing Performance 2
Eject Speed
The default eject speed setting is 200 µl/min for the standard autosampler and 
1000 µl/min for the preparative autosampler. 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 plunger 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.
