摘要：

Some fundamental characteristics of a furnace atomization plasma excitation (FAPES) source are presented and discussed. For this source, the electron ionization rate is 120 times higher in He compared with Ar resulting in easier ignition and operation with He. Background spectra are dominated by emission features from CO+, N2+, N2, OH, NH, and He I. Emission is most intense near the central electrode and furnace walls. Excitation temperatures for Fe I are in the range of 3000-4500 K.
