ABSTRACT:
Organic samples from a liquid chromatograph are deposited on a conveyor belt which transports them into a vacuum chamber at the entry end of a mass spectrometer. The samples are ionized directly on the belt by particle bombardment or by means of a laser beam. Ionization is enhanced by applying an oxide layer to the belt, by neutralizing the image force, and by vaporizing alkali atoms on the belt to reduce the ionization potential.
