They do have the capability to take any sample and analyse it to confirm to a high certainty, every component in sample. As part of our accreditation schemes they take part in, their costs for 15 days of work runs over 200,000 GBP. If we send them samples to analyse, the standard rate for the lab is around the 15,000 GBP per day. That is an extreme case because of the samples we deal with, but labs aren't cheap to run, especially if you want a comprehensive set of tests conducted.
I'm sorry but this is massively overstating the costs, probably because of the laboratories you work in. Off the top of my head you'd be looking at £5-10,000 to get a university to do it, some may even do it for a lot less. It's unlikely anyone will offer any guarantees as to what they might find, but anyone with a high-resolution mass spectrometer (and TOFs and Orbitraps are everywhere these days) would be able to have a look at it see what they could find. A standard C18 column and simple gradient would no doubt be fine, and peak shape isn't really an issue, it's not like they want quantitation or anything.
Whether they would do it is a different question entirely and it's certainly something that would have to be discussed internally beforehand. We certainly wouldn't just take a powder of some guy who found it by the road and analyse it. If that ever came up I would probably be contacting the police, ethics board and relevant government agencies to make sure everything was ok.
The other option would have been to contact Thermo, Waters, Bruker etc. and got them to do it, likely at a reduced cost because of the added benefit of getting their names and products in the news (Thermo are trying to push the Fusion at the moment).
