Description
Summary:Considering the problem that atmospheric ionization cannot ionize some low polarity materials, the method using atmospheric sampling glow discharge to ionize those was proposed. Designed A simple method was designed to discharge in which an alternating current high voltage power was applied to the tube lens in the first stage vacuum of the homebuilt atmospheric pressure interface-single quadrupole mass spectrometer. The low polarity materials was drifted in the discharging region and ionized, and detected by the quadrupole mass analyzer. The experiment showed that the method can be used to detect Aldrin (organochlorine pesticide) that cannot be ionized by electrospray and atmospheric chemical ionization, and the intensity of ions in negative ion detection mode was 40 times stronger than that in positive ion dection mode.
