Lab 2: Confirmatory Testing by Mass Spectrometry in Forensic Context
The confirmatory testing in forensic science is most often done by using mass spectrometry based methods. The mass spectrometry allows for determination of structure and identity of the drug and its metabolites. In this lab, the mass spectrometry is used to detect the presence of a common medication, aspirin and its metabolite, salicylate.
