Abstract
There is disclosed an ion source for use in a mass spectrometer. The ion source has an ionization chamber, a pumping means for continuously pumping liquid sample, an inlet tube whose front end is located inside the ionization chamber to introduce the liquid sample delivered from the pumping means into the ionization chamber, a means for ionizing the sample introduced into the ionization chamber, and an exhaust pipe connected with the inlet tube. The ion source further includes a means for applying a pressure on the superfluous sample in the exhaust pipe by employing a gaseous material. Thus, the flow rate of the sample introduced into the ionization chamber through the inlet tube is stabilized.
