Troubleshooting
While random air spikes may not affect the analysis, constant air spikes are a problem.
One of the most common causes of constant air spikes is the introduction of air into the
line due to the exhaustion of the reagent. Make sure the reagent transmission lines are at
the bottom of the containers.
6.3.2 Patterned air spikes
If the air spikes seem to be present in every peak at the same location, air is probably
being injected along with the sample slug. Check the valve timing of the method by
running the dye. Refer to section 6.1 on page 64.
