GAs can be used as the electron source in electron impact ionization source applications. This technology has the advantage of performing as a cold ionization source, which eliminates pyrolytic effects that occur when the heat generated by the filament chemically changes the unknown substances to be identified.

PHOTONIS’ 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. Because each of the millions of pores produce electrons, the resultant electron flux is extremely uniform and dense.
