Nah, we do this daily for ID of chemicals as part of a GMP release. We use a handheld Raman spectrophotometer--just point it at the stuff and it gives you the spectrum.
Here is a paper detailing its use in determining methanol content of ethanol spirits: https://pubs.rsc.org/en/content/articlelanding/2019/an/c8an01702f#!divAbstract https://pubs.rsc.org/en/content/articlelanding/2019/an/c8an0...
