Forensic Drug Testing HowStuffWorks

A spectrophotometry machine emits UV and IR rays, and then measures how the sample reflects or absorbs these rays to give a general idea of what type of substance is present A more specific way to test drugs is with the microcrystalline test in which the scientist adds a drop of the suspected substance to a chemical on a slide
