Abstract
An object of the present invention is to provide a mass spectrometer having an optical ion transport system where the efficiency for generating and converting fragment ions can be increased, and which can transport the generated fragment ions efficiently to the rear stage, and in order to achieve this object, the mass spectrometer for ionizing a sample in an ionization chamberand drawing the ionized sample into a mass spectrometric chamberis provided with an ion transport optical system having electrodes-and-provided so as to surround an optical ion axis, and is characterized in that the above described electrodes-and-have an inclined surface which is inclined so as to spread in the direction in which ions progress along the above described optical ion axis.
