Could anyone recommend a lab to send a few assemblies to for evaluation of foreign substance?

We had a few assemblies that are conformal coated come back from a customer claiming their is corrosion from water exposure. After evaluation I do not believe water was the liquid our assemblies came into contact with but some abrasive chemical. I'd like to send the boards somewhere for evaluation to see if a lab could tell from the residue left, what actually came into contact with our assemblies.
