Within the ionization chamber the remaining molecules—a mix of your cell stage parts and solutes—endure ionization and fragmentation. The mass spectrometer’s mass analyzer separates the ions by their mass-to-charge ratio (m/z). A detector counts the ions and shows the mass spectrum.  You will understand why it grew to become a preferred stra
