Hello
We have an agilent ultivo qqq and last week when trying to run a checktune it failed giving a message saying calibrant bottle is empty or nebulizer is clogged. Nevertheless the calibrant bottle is definitely not empty, and the nebulizer also doesnt seem clogged. There is no backpressure, the analysis are still giving correct results, and the shape of the nebulizer spray seems correct.
Any clue what we can try to do to troubleshoot it?
Thanks!
