We used EAG two years ago to identify a mystery liquid in an etcher.  https://www.eag.com/

Subject: [labnetwork] ICP analysis for unknown grease

Dear colleagues,

I have found a an unknown contamination in the loadlock of our the UHV system. It has a white, greasy, soft  texture. I'd like to know the elemental analysis of it since after wiping the system with IPA and baking it the vacuum didn't improve and I am afraid it must have left residuals.  
Would you know any company that offers elemental analysis/ ICP to identify unknown substances?

Thank you,
Saba
