TQD - Sample cone Problem?
Good days I am working with a new TQD in newborn screening (aminoacids and carnitines).The problem is that the sample cone gets dirty very much but only in the internal part (dun, like to burned).I know that normal is that the external part (cone and source) exposed to the spray gets dirty, but they are perfectly clean and polished.I attach photos.Thanks Manuel Zelaya

Looks like normal "ion burn" to me.
What makes you think the cone is dirty ?
Has your sensitivity diminished ?
Does your sensitivity improve following sample cone cleaning ?
