How is FTIR used for drug testing? Is it used to test for contamination based on the spectrum profile?
- nikmobi 8y agoNot an expert, but if you can test for contamination why wouldn't you be able to test for the drugs themselves? Raman spectroscopy[1] is one that I know of that is frequently used to determine chemical composition. Spectroscopy in general still amazes me.

You can even measure the amounts of various chemicals in solution, but that would require complex calibration. In this case you are basically writing ML system that is trying to fit various peak heights/areas to amount of compound.
