CAUSE

The orange PEEK tubing does not reach down to the bottom of the 30-mL Nalgene fluidics bottle; therefore, air is drawn instead of sample.        

FIX or WORKAROUND

1. Open the fluidics door.
2. Loosen the finger-tight fitting (PEEK on the left is for reference syringe; right is for sample syringe).
3. Pull some tubing through above the finger-tight from the instrument interior.
4. Feed it down into the bottom of the 30-mL bottle.
5. Tighten the finger-tight to lock in place.
6. Close the fluidics door.
7. Purge fluidics several times if needed, and check flow.
