The primary function of a vacuum system in mass spectrometry is to create and maintain a low-pressure environment within the instrument. This low-pressure condition is vital for several key processes integral to mass spectrometric analysis, including ionization, ion manipulation . Mass Spectrometry (MS) stands as a foundation in modern analytical chemistry, offering unparalleled capabilities in identifying and quantifying molecules with remarkable precision. Molecular ions are produced in a conventional source by electron bombardment of hydrogen gas. 451] The. A vacuum system is indispensable to the free flight of ions in a mass analyzer. Beginning with the simple question 'Why do we need vacuum' we will move on to discuss the types of vacuum technology typically used on mass specs, and then review the evolution of vacuum subsystems from the. Mass Spectrometry is used for many analytical purposes including: In analytical laboratories, the most common applications involving a mass spectrometer are Pharmaceutical, Biopharma, Drug screening, Environmental testing, Food & beverage testing, Petrochemical.
