This patent describes a portable mass spectrometer. It comprises: a vacuum chamber; a source of material to be analyzed; an ionization chamber coupled to the vacuum chamber and adapted to receive material to be analyzed from the source and to form an ion beam comprising ions of the material; an adjustable electrostatic sector in the vacuum chamber generally aligned with the ion beam emerging from the ionization chamber; mechanical means for adjusting the electrostatic sector to focus the ion beam; an adjustable magnetic sector in the vacuum chamber generally aligned with the path of the ion beam emerging from the electrostatic sector; mechanical means for adjusting the magnetic sector to focus the ion beam; and detection means for detecting the ion beam focused by the electrostatic sector and the magnetic sector.
