Glow discharge mass spectrometry (GDMS) is associated with two closely related techniques for the characterization of ion populations in glow discharge plasmas The materials scientist is familiar with GDMS as a tool for plasma processing diagnostics whereas the analytical chemist is familiar with GDMS as a method for direct solids analysis The present chapter will focus on GDMS as a
Atomic Spectroscopy • Atomic spectroscopy refers to measurement of elemental concentrations via optical processes of absorption emission or fluorescence as exemplified by AAS AES and AFS • Atoms change states when electrons move to different orbitals • Mass Spectroscopic techniques such as inductively coupled plasma-mass spectrometry or glow discharge-mass spectrometry are also
