In the ionization chamber the remaining molecules—a combination with the cell period parts and solutes—bear 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.The concentration of polynuclear aromatic hydrocarbons (P
