Syringe is rinsed with solvent.
GC inlet liner is clean and deactivated.
GC inlet liner is correct type for injection technique.
GC inlet septum type is correct and the septum is less than 200 injections old.
Correct septum nut is installed in GC inlet.

Running a sample
To operate your 7683 Automatic Liquid Sampler:
1. Install a clean syringe. See Installing A Syringe on page 16.
2. Fill the solvent bottles and load them into the turret. See Preparing The Solvent And
Waste Bottles on page 13.
3. Load the waste bottles into the turret. See Preparing The Solvent And Waste Bottles on
page 13.
4. Load the sample vials into the turret or into the tray. See Preparing Sample Vials on
page 9.
5. Load (or program) the GC sequence. See your 6890 GC or Agilent ChemStation
documentation.
6. Run the GC sequence.
When the GC becomes ready, the 7683 Automatic Liquid Sampler begins the injections.
