Mass Spectrum of Fentanyl

Caption

This is the mass spectrum for the synthetic opioid, fentanyl. The mass spectrum is like a molecular fingerprint, and is used to identify unknown compounds. The red lines represent the charged fragments of the molecule created during analysis. The vertical axis shows the relative intensity, or amount, of each fragment, while the horizontal axis shows the mass-to-charge ratio for each fragment.
