particle beam interface
A particle beam interface (PB) is a method for coupling liquid
chromatography to mass spectrometry in which the effluent is passed
through a heated capillary to form an expansion of vapor and aerosol
particles.
After passing through a skimmer, the beam impinges on a heated surface
to form ions through chemical ionization at the surface or ionization of
the resulting vapor in a CI or EI source.
