What is Mass Spectrometer?

A mass spectrometer is an analytical instrument that separates ions according to their mass-to-charge ratio (m/z) after vaporizing and ionizing a sample. The technique involves ion generation (e.g., electron impact or electrospray), acceleration in an electric field, deflection by a magnetic field, and detection to produce a mass spectrum showing the relative abundance of each ion. Mass spectrometry is used to determine molecular masses, molecular formulas, isotopic abundances, and structural information about complex organic and inorganic compounds.
