5 Optimizing Performance
Fast Injection Cycle and Low Delay Volume
General Recommendations for Fast Injection Cycle
Times
As described in this section, the first step to provide short cycle times are
optimizing the chromatographic conditions. If this is done the autosampler
parameter should be set to:
• Overlapped injection mode
• Increase of draw and eject speed for large injection volumes
• Add at last run a blank, if overlapped injection is used
To reduce the injection time, the detector balance has to be set to OFF.
