Things like this have been used for a long time at places where you can bring scrap metal.
But when you deal with complex substances spectrophotometers cannot do the job. This is why GC/MS, HPLC is used by labs to do the job not spectrophotometers.
So my meat head question , is it even scientifically possible too make a device like this? (Portable hand held)
These things are about as reliable as a labmax. They are helpful to a small degree, but there is much room for error. They basically work like this; if you have a known standard that you are using and you test something that it is supposed to be, it would tell you if it is a match. Example, if you received a batch of Watson test cyp from the Internet and had a Known standard of it it would be able to tell you it is a match assuming Watson never changes their formula.
