Cones before and after

A sample cone looks like this after you clean it:
And a skimmer cone looks like this after some samples:
I think that is permanganate built up on there. Anybody else have an idea?

I dig this blog, man. (I don't have an answer to your question, however)

You didn't digg it?

Permanganate should be broken down by the plasma, and cone residue should be buffered in fO2 at Ni/NiO.

What solution were you running? Also, if your sampler cone isn't screwed on tight enough, it will overheat and roast, sending copper everywhere (at least on an Agilent).

What is fO2 at Ni/NiO? Solutions are environmental water/sediment samples. Sampler cone is screwed on tight. It's a Thermo. The dirty one is the skimmer.
