2. The syringe dispenser aspirates the “flush volume” from the

sample vial to fill the sample line with sample and remove
wash solvent.

Full loop injection: flushing sample lines and needle.

3. The injection valve is switched into the Load

position,

placing a distinct sample front at the inlet of the sample loop.

Full loop injection: switch injection valve to Load.
