Sampling and analysis of suspended particles and vapors by continuum source particle beams

Two continuum source particle beam methods are proposed for the on-line measurement of suspended particles or material which is suspendable in a gas. The first method can be used to size separate the various molecular and particulate species present in the beam. The second method is used to obtain a molecular composition analysis of individual beam particles or a composition distribution for a sample containing a large number of particles. The two methods are complementary and can be used together to obtain molecular composition analyses of size-separated beam particles
