Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a mol

Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a molecule. The x-axis of a mass spectrum represents the masses of ions produced (m/z) The y-axis represents the relative abundance of each ion produced
