I'm in doubt they detected anything. It is unlikely that you will notice any peaks from contamination. Raman spectra itself is very dim, it is a great challenge to detect Raman scattering even from pure substances, say water or salt crystal. And brighness of Raman scattering obviously proportional to the amount of substance studied. If it is some weak water solution, then water lines will be magnitude orders brighter than from dissolved substance.
With Raman you have to separate light source line from very dim scattering lines. It is like trying to make a photo of a stars in daylight. And moreover you have to do the same again to separate dissolved substance scattering from O-H water bonds scattering f.e.
If you have a mix of numerous substances dissolved in water, then you get a lot of tiny peaks at the noise level mixed alltogether.
Raman spectrometer is not some magic device that print out exact composition of scanned specimen. It is a very useful device that could give you some clue in some circumstances. But to make it useful you have to know how to use it properly and how to correctly interpret results.
Even with that X-ray (or laser) gun that show composition of alloy as a list of elements found in measured metal object things are not that simple. You could get high zinc amount just because the thing is zinc-plated. And it does not show you crystal structure of ally. It is hard to distinguish martencite from austenite stainless steel f.e. It gives you a clue, and then you have to use your brain and knowledge to get some real result.
As I see proper study of not-a-vaccine:
- do a mass-specrometry and get a full list of elements with concentrations.
- Do quantative chemical analysis on most probable salts of metals from the list. Here we already have some chemical formulas and concentrations, so could decide could they be harmful or not. Also we could strike out known things from initial elements list.
- Depending on what left do quantative organic chemistry analysys to find out simple organic things like alcohols, ethers, cyclic things and so on.
- Then chromatography for complex organic compositions. If things like RNA/DNA detected, then do whatever decoding to find out real sequence.
- With complex organic things do Raman to find out exact isomeres and structure.
- Do all that until initial elements list become empty.
Eventually we will have exact composition of not-a-vaccine specimen with all substances found and their concentrations.
Such independent research is perfectly possible for any more or less equipped biochemical lab. It will take some time and money for spendables, but it is absolutely doable and could have been done in passed years easily. It hardly will be accepted by "official" science due to "legal" issues from obtaining samples to non-granted use of lab equipment, but if the goal is truth and not grant money, h-index or publication in famous journal that does not matter.
