As far as 'purchasing analytical equipment' to figure out what you have. The cheapest possible spectrometer I can think of, and have used in the past, is an LC/MS machine. These are not easily found, they are most likely 'watched' by alphabet agencies, and are extremely expensive. Unless you happen to know a retiring chemist who will gladly give you his, or sell you one for cheap.
Even in that rare circumstance, you must be able to order the proper type of water (deionized, specially made for LC/MS equipment or the machine will get clogged within a week), you'll need other highly-pure and expensive solvents to use, all of which can only be purchased by someone with the appropriate license from major manufacturers...yes, even outside the US.
Take home: a reagent test kit with the strips is the best you'll be able to do on your own. Unless you are willing to submit a tablet to an analytical testing facility and pay upwards of $200 for a result that's based on a peak they see in the spectra, that they can directly compare to known literature about that peak for that specific compound....they will never be able to tell you the 'exact amount of X in tablet Y.
So right thepianist.
………………………….LC/MS spectrophotometer is > 50K and requires all the specialized equipment from software/liquids/gases/standards etc - not to mention the knowledge of how to use it.
This is type of equipment used in quality product purity and control/forensics/ etc.
I used one- it's out of the normal consumer realm.
Even if you have a buddy who has access to one- it takes the right column ( used for component separation ) and LC/MS conditions to get it to work- the person would need to be in the business of drug quality control/research; to know how to do it.
