Maintenance
This section contains some suggestions for ensuring good performance of your
HP 7683. The maintenance interval varies with the use of the instrument.
Caution
Do not use any lubricants on the HP 7683 Automatic Liquid Sampler. They may
effect the chemical performance of the GC and damage the instrument.
On an occasional basis:
Clean the surface of the tray arm, gripper, gripper jaws, and tray quadrants.
Clean the needle guide and nearby surfaces of the injector. Dust and dirt
accumulate in these areas and can be picked up by the syringe needle and
carried into the inlet.
Clean the surface of the injector. Vacuum off any dust that builds up around
the vents.
Make sure the injector mounting post is tight.
Make sure the tray mounting screws are tight.
Make sure the knurled nut on the top of the turret is tight.
Be sure all the cables are securely attached.
