In the ionization chamber the remaining molecules—a mix from the mobile phase components and solutes—undertake ionization and fragmentation. The mass spectrometer’s mass analyzer separates the ions by their mass-to-demand ratio (m/z). A detector counts the ions and displays the mass spectrum.Since the stationary stage is polar, the cell phase
