EGAs
can be used as the electron source in electron impact ionization
sources. This technology has the advantage of performing
as a cold ionization source. Eliminating pyrolytic effects
that occur when the heat generated by the filament chemically
changes the unknown substances to be identified.
BURLE’s
patented ELECTROGEN™ Electron Generator Arrays (EGAs)
consist of millions of precision glass tubes fused together
to produce a uniform and mechanically rigid structure. They
are processed such that, when a voltage is applied across
the thickness, each pore produces a beam of electrons. With
each of the millions of pores producing electrons, the resultant
electron flux is extremely uniform and dense.
